CIB1 (Calcium and integrin binding 1) is regulatory protein with 50% homology to calmodulin and calcineurin B, that encodes a member of the calcium-binding protein family. The specific function of this protein has not yet been determined, however this protein is known to interact with DNA-dependent protein kinase and may play a role in kinase-phosphatase regulation of DNA end joining. Also CIB1 is widely expressed and binds to a number of effectors, such as integrin alpha IIb, PAK1, and polo-like kinases, in different tissues. Source: Recombinant protein corresponding to aa1-191 of human CIB1, fused to His-tag at N-terminal expressed in E. coli.
