Anti-HAX1 Rabbit Polyclonal Antibody (Cy3®)

Supplier: Bioss

RelevanceHAX1 associates with HS1, binding to its N-terminal region. It is also known to associate with PKD2 (involved in polycystic kidney disease) and with cortactin/EMS1. HAX1 is also reported to bind to hairpin structures in vimentin and DNA polymerase beta mRNAs, so may play a role in mRNA stability and transport. It may also function in promoting cell survival. Defects in HAX1 are the cause of autosomal recessive severe congenital neutropenia 3 (SCN3) also called Kostmann disease.
