Generic protein structure example

Calcium and integrin-binding protein 1 is a protein that in humans is encoded by the CIB1 gene.[1][2][3]

The protein encoded by this gene is 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. This protein also interacts with integrin alpha(IIb)beta(3), which may implicate this protein as a regulatory molecule for alpha(IIb)beta(3).[3]

Interactions

CIB1 has been shown to interact with RAC3,[4] PSEN2,[5] DNA-PKcs,[6] UBR5[7] and CD61.[1]
