Generic protein structure example

S100 calcium-binding protein P (S100P) is a protein that in humans is encoded by the S100P gene.[1][2][3]

Function

The protein encoded by this gene is a member of the S100 family of proteins containing 2 EF-hand calcium-binding motifs. S100 proteins are localized in the cytoplasm and/or nucleus of a wide range of cells, and involved in the regulation of a number of cellular processes such as cell cycle progression and differentiation. S100 genes include at least 13 members which are located as a cluster on chromosome 1q21; however, this gene is located at 4p16. This protein, in addition to binding Ca2+, also binds Zn2+ and Mg2+. This protein may play a role in the etiology of prostate cancer.[3]

Interactions

S100P has been shown to interact with EZR[4] and RAGE.[5] The interactions between S100P and RAGE are disrupted by cromolyn[6] and pentamidine.[5]
