OS4 Antibody (2230C1a) is a high quality monoclonal OS4 antibody (also designated OS4 antibody) suitable for the detection of the OS4 protein of human origin. OS4 Antibody (2230C1a) is available as the non-conjugated anti-OS4 antibody. OS4, also known as CTDSP2 (Carboxy-terminal domain RNA polymerase II polypeptide A small phosphatase 2) or SCP2, is a 271 amino acid nuclear protein that is implicated in the development of sarcomas. Expressed ubiquitously with particularly high expression observed in the pancreas, OS4 functions in the regulation of androgen-dependent transcription by globally silencing neuronal genes. OS4 contains one FCP1 homology domain and, acting as a Smad2/3 linker phosphatase, can enhance Smad2/3 signaling. Through its ability to interact with Smad2/3, OS4 contributes to the final signaling events in the Smad pathway and, thus, is thought to be a crucial component in the metastasis of certain cancers. Overexpression of OS4 may lead to the development of primary sarcomas, as well as brain tumors.
