Summary: Predicted to enable RNA polymerase II CTD heptapeptide repeat phosphatase activity. Acts upstream of or within negative regulation of G1/S transition of mitotic cell cycle; negative regulation of cell differentiation; and negative regulation of protein phosphorylation. Predicted to be located in nucleoplasm. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; immune system; and integumental system. Orthologous to human CTDSP1 (CTD small phosphatase 1). [provided by Alliance of Genome Resources, Dec 2024]

What's a GeneRIF?

Consistently, the authors observed increased AKT phosphorylation and angiogenesis followed by enhanced tumorigenesis in Ctdsp1 (which encodes SCP1) gene - knockout mice. Importantly, they discovered that the membrane localization of SCP1 is crucial for impeding angiogenesis and tumor growth, and this localization depends on palmitoylation of a conserved cysteine motif within its NH2 terminus.
Title: Palmitoylated SCP1 is targeted to the plasma membrane and negatively regulates angiogenesis.
Golli-BG21 enhanced SCP1/GIP phosphatase activity, whereas PKCalpha-phosphorylated BG21 inhibited its activity, suggesting a potential role of BG21 as a molecular switch ("quick-brake mechanism") on SCP1/GIP.
Title: Regulatory effect of the glial Golli-BG21 protein on the full-length murine small C-terminal domain phosphatase (SCP1, or Golli-interacting protein).
Findings suggest that SCP1 may inhibit the osteoblastic differentiation induced by the BMP-Smad axis via Runx2 by suppressing downstream effector(s).
Title: Suppression of BMP-Smad signaling axis-induced osteoblastic differentiation by small C-terminal domain phosphatase 1, a Smad phosphatase.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
