CIB1 (5A1F) Antibody

CIB1 (Calcium and integrin binding 1) is a 191-amino acid protein (~21kDa), belongs to the calcium-binding protein family. CIB1 is known to interact with DNA-dependent protein kinase and may play a role in kinase-phosphatase regulation of DNA end joining. CIB1 is an EF-hand-containing protein that binds multiple effector proteins, including the platelet alpha(IIb)beta(3) integrin and several serine/threonine kinases and potentially modulates their function. CIB1 regulates platelet aggregation in hemostasis through a specific interaction with the alpha(IIb) cytoplasmic domain of platelet integrin alpha(IIb)beta(3). CIB1 is also ubiquitously e, Xenopus/Amphibian,pressed activating and inhibiting protein ligand of the InsP3R.
