The human Cullin family of genes consists of Cul-1, Cul-2, Cul-3, Cul-4a, Cul-4b, and Cul-5. Among the 6 members, Cul-1 and Cul-2 are very well characterized. Cul-2 is homologous to the Saccharomyces cerevisiae cdc53 gene. Studies have shown that Cul-1 forms an E3 ubiquitin-ligase, called the SCF complex (Skp1 and F-box protein such as bTrCp or FWD1), which controls the proteolysis of G1 cell cycle regulatory proteins.

Cyclins are a family of proteins which function as the regulatory subunits of cyclin/cyclin-dependent kinase (Cdk) holoenzymes, mediating entry into and progression through the cell cycle. Each cyclin is expressed in a temporal fashion during the cell cycle, partnering with a specific Cdk to activate its protein kinase activity. The most well defined mitotic cyclins are: cyclin D, which partners with cdks 4 and 6 during early G1 phase; cyclin E, which activates Cdk2 in the G1 to S phase transition; cyclin A, which utilizes Cdks 1 and 2 during progression through S phase and into G2; and cyclin B, which activates Cdk1 in M-phase promotion.

CLIP (class II-associated invariant chain peptide) is an important peptide in the MHC-II antigen processing pathway, formed by the enzymatic cleavage of amino acids 81-104 from the invariant chain. During MHC-II synthesis in the ER and transport to endocytic vesicles, the antigen binding site of MHC-II is obstructed by the presence of the invariant chain. As the MHC-II complex moves through the Golgi, the invariant chain is degraded, leaving the CLIP fragment in the MHC-II peptide binding groove. CLIP is eventually displaced by the loading of antigenic peptides, followed by presentation on the APC cell surface to CD4+ T-cells.

Mcl-1 is a member of the Bcl-2 family that possesses anti-apoptotic activity. Mcl-1 is an immediate-early gene activated by the GMCSF as well as IL-3 signaling pathways and plays an important role in the viability response of these cytokines. Similar to all Bcl-2 family members, Mcl-1 contains BH1, BH2, and BH3 domains; however, unlike other members of this family, Mcl-1 has an extended N-terminal domain rich in PEST sequences, which probably accounts for the short half-life of this protein.

Bim is a critical regulator of lymphocyte homeostasis, acts as a barrier against autoimmune disease and is necessary for the apoptotic response to certain stress signals.

Actin is one of the major proteins (~42 kDa) of the cytoskeleton. It regulates contractile potential in muscle tissues and helps to control the shape as well as the motility of non-muscle cells. Actin is expressed in all eukaryotic cells which makes it a useful loading control in Western blotting experiments. In higher eukaryotes, there are six isoforms of actin: Three alpha-actins (α-skeletal, α-cardiac, α-smooth muscle), one β-actin (β-non-muscle) and two γ-actins (γ-smooth muscle and γ-non-muscle). Actin isoforms show >90% overall sequence homology.

The caspases are a family of cysteine proteases that cleave after certain aspartate residues, and are primarily recognized as mediators of apoptosis. caspases are synthesized as inactive zymogens that can be cleaved to form active enzymes following the induction of apoptosis by stress or death receptors. Initiator caspases (e.g. caspase-8 and -10) are activated by dimerization of the zymogen on a dedicated adaptor protein. These activated initiator caspases in-turn cleave downstream effector or ?executioner? caspases (e.g. caspase-3, -6, and -7) in a cascade-like manner, which cleave key cellular proteins that lead to the morphological changes associated with apoptotic cell death.

MD-2 is a member of the Toll/interleukin-1 receptor (TIR) family, a group of proteins that include the Toll-like receptors (TLRs). TLRs recognize different pathogen-associated molecular patterns, thereby linking the innate and adaptive immune responses.

Lipid peroxidation is a well-established mechanism of cellular injury in both plants and animals, and is used as an indicator of oxidative stress in cells and tissues. Lipid peroxides, derived from polyunsaturated fatty acids, are unstable and decompose to form a complex series of compounds. These include reactive aldehydes, of which the most abundant is malondialdehyde (MDA). Therefore, measurement of malondialdehyde is widely used as an indicator of lipid peroxidation. Increased levels of lipid peroxidation products have been associated with a variety of chronic diseases in both humans and model systems.

A QuantiZyme™ Assay System. The MMP-14 Fluorometric (also known as fluorimetric) Drug Discovery Kit is a complete assay sytem designed to screen for inhibitors of matrix metalloproteinase-14 (MMP-14, membrane-type matrix metalloproteinase 1, MT1-MMP) using a quenched fluorogenic peptide: OmniMMP™ fluorogenic substrate Mca-Pro-Leu-Gly-Leu-Dpa-Ala-Arg-NH. Mca fluorescence is quenched by the Dpa group until cleavage by MMPs at the Gly-Leu bond separates the two moieties.

Quenched fluorogenic substrate for cathepsin D (kcat/Km=1,09×10 M-1s-1) and cathepsin E (kcat/Km=1,56×10 M-1s-1). Mca fluorescence is quenched by the Dnp group until cleavage separates them. Activity of the two enzymes on this substrate can be distinguished by the use of Ascaris pepsin inhibitor, which inhibits cathepsin E, but not cathepsin D. This substrate is also cleaved by MMP-2, MMP-3, MMP-9, but not MMP-1 nor MMP-13. This substrate is useful for inhibitor screening and kinetic analysis. Ex.: 320-340 nm, Em.: 393-420 nm. Mca-Pro-Leu-OH (BML-P127) can be used to calibrate for Mca fluorescence.
