Protein Function and Prediction

Ctdspl encodes the ubiquitously expressed small C-terminal domain (CTD) phosphatase 3 (SCP3) (1), a member of the SCP family of phosphatases that functions in dephosphorylates serine five of the CTD consensus sequence on RNA polymerase II (2).  SCP3 has been identified as a tumor suppressor of epithelial malignancies, possibly through the dephosphorylation of ppRB that blocks the cell cycle at G1/S (3).  Alterations in CTDSPL are also linked to early and late-onset breast carcinoma (4), non-small cell lung cancer (5;6), cervical carcinoma  (7;8), and dysplastic lesions of the head and neck (9). Along with SCP1 and SCP2, SCP3 can dephosphorylate Smad1 to inhibit BMP signaling and subsequent osteoblast differentiation (10;11).  Also they can serve as a Smad2/3 linker to enhance TGFβ signaling (12;13).
