The TLRs (Toll-like receptors) are a group of evolutionarily conserved pattern recognition molecules that play a key role in host defense during microbial infection by regulating both innate and adaptive immune responses. TLRs are type I transmembrane proteins with ectodomains containing interspersed leucine-rich repeat (LRR) motifs that are involved in the recognition of various microbial ligands.

The cannabinoid receptors CB1 and CB2 are GPCRs named for their signaling function in response to cannabinoid drugs such as Delta9-tetrahydrocannabinol (Delta9-THC). In addition to Delta9-THC and its synthetic analogs, CB1 and CB2 receptors are bound by endogenous eicosanoid ligands (e.g. anandamide), and signal via Gi/o alpha subunits to regulate adenylyl cyclase activity (generally inhibitory), ion channel activation, intracellular Ca2+ levels, nitric oxide synthase activation, and immediate early gene expression. CB1 and CB2 signals in turn regulate neurological and immunological functions such as inhibition of neurotransmitter release and immune cell migration, antigen processing, and cytokine production.

DNA-topoisomerase II, also known as Topo II or Top 2, is a multifunctional nuclear enzyme required during DNA replication, chromosome disjunction at mitosis, and other DNA-related activities because of its ability to alter DNA supercoiling. In mammalian cells, Topo II consists of two isozymes, Topo II-alpha (170kDa) and Topo II-beta (180kDa) and expression and localization of each isoform are distinct and stage specific during the cell cycle. Topo II-beta is expressed constitutively throughout the cell cycle, whereas the expression of Topo II-alpha is cell cycle-regulated, peaking in G2 to M phase and declining to a minimal level at the end of M phase. DNA-topoisomerase II is the target of some of the most active drugs used in chemotherapy and has been shown to have a critical role in neural development.

The nucleosome is made up of four core histone proteins (H2A, H2B, H3 and H4) and is the primary building block of chromatin. The core histones form an octamer, which is made up of one H3-H4 tetramer and two H2A-H2B dimers. The N-terminal tail of core histones undergoes different post-transcriptional modifications including acetylation, phosphorylation, methylation and ubiquitination. These modifications occur in response to cell signal stimuli and have a direct effect on gene expression.

The cell division cycle (cdc) group of proteins consists of many protein classes, including cyclin dependent kinases (Cdks), phosphoprotein phosphatases, mitogen activated kinases, small GTPases, and cyclins. These proteins play a central role in regulating progression through the cell cycle through the formation and/or modification of key substrates. Cdc42 belongs to the Rho-family of GTPases, and promotes actin polymerization to form filopodia. Cdc25A is a dual-specificity phosphatase that acts on phosphorylated threonine and tyrosine residues of Cdks, leading to binding and activation of their partner cyclins.

Nuclear factor erythroid 2-related factor 2 (Nrf2) is a transcription factor, which regulates the expression of many detoxification and antioxidant enzymes. Nrf2 can potentially play a significant role in adaptive responses to oxidative stress. Nrf2 belongs to the Cap N Collar subfamily of basic leucine zipper (CNC-bZIP) transcription factors. The NF-E2 related family comprises of Nrf1 (TCFII), Nrf2, and Nrf3 and these proteins heterodimerize with Maf proteins to bind to Maf recognition element (MARE). Under normal conditions, Nrf2 is inactive and localized in the cytoplasm through its association with Keap1. When cells are exposed to electrophiles or oxidative stress generating agents cytoplasm localization of Nrf2 is inactivated and Nrf2 translocates into the nucleus and binds to specific DNA sequence elements known as NF-E2 binding site, Maf recognition element (MARE), stress response element or anti-oxidant response element (ARE). Studies have investigated the role of Nrf2 in urinary bladder carcinogenesis, pulmonary fibrosis, and smoke-induced emphysema. A study reported Nrf2-mediated ARE transcription to be a likely target of preventative therapy in neurodegenerative disorders such as Huntington's disease.

Monomeric G-protein Ras functions as a molecular switch linking receptor and nonreceptor tyrosine kinase activation to a number of downstream signaling pathways. Oncogenic mutations, which occur in approximately 30% of all cases of human cancer, lead to the stimulation of proliferation and the inhibition of apoptosis.

Protein Kinase C (PKC) is a large superfamily of serine/threonine kinases that mediate essential cellular signals required for activation, proliferation, differentiation and survival. There are at least ten PKC isotypes that are closely related in structure but that have distinct patterns of tissue distribution and function. The PKC isotypes can be subdivided into three classes based on primary structure and biochemical properties. These are: classical or conventional PKC isotypes (cPKC), novel PKC isotypes (nPKC) and atypical PKC isotypes (aPKC).

PKA (Protein Kinase A), also known as cAMP-dependent protein kinase, phosphorylates serine or threonine residues in target protein in response to elevated levels of cAMP. Inactive PKA exists as a tetrameric protein composed of two regulatory (R) subunits and two catalytic (C) subunits. Activation occurs when two cAMP molecules bind to each R subunit which causes a conformational change that releases the active C subunits.

Calreticulin (CRT) is a multifunctional, multi-compartmental protein most abundant in the ER lumen. CRT contains the ER-retrieval sequence, KDEL, and has been best characterized as a soluble molecular chaperone of new or misfolded proteins and a Ca2+- binding protein. Both CRT and its membrane bound homolog, Calnexin (CNX) interact with proteins and glycoproteins that have monoglucosylated N-glycans. The CRT/CNX cycle promotes correct folding, inhibits aggregation of folding intermediates, blocks premature oligimerization, regulates ER degradation, and provides quality control by preventing incompletely folded glycoproteins from exiting to the Golgi complex.

Ubiquitin (Ub) plays a very important role in regulated non-lysosomal ATP dependent protein degradation. The protein to be degraded is conjugated to Ub and the ubiquinated protein is then selectively degraded by the 26S complex, a multicatalytic cytosolic and nuclear protease. The Ub-proteasome proteolytic pathway, which is a complex process, is implicated to be of great importance for regulating numerous cellular processes.
