CTDP1 - CTD phosphatase subunit 1 Gene
Also Known as FCP1; CCFDN
Species: Homo sapiens
About CTDP1
This gene has 8 transcripts (splice variants), 1 gene allele, 206 orthologues and is associated with 4 phenotypes. Ubiquitous expression in testis (RPKM 8.7), colon (RPKM 6.0) and 25 other tissues.
Summary
This gene encodes a protein which interacts with the carboxy-terminus of the RAP74 subunit of transcription initiation factor TFIIF, and functions as a Phosphatase that processively dephosphorylates the C-terminus of POLR2A (a subunit of RNA polymerase II), making it available for initiation of gene expression. Mutations in this gene are associated with congenital cataracts, facial dysmorphism and neuropathy syndrome (CCFDN). Alternatively spliced transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Feb 2011]
