What is the official name of the CTDP1 gene?
The official name of this gene is “CTD (carboxy-terminal domain, RNA polymerase II, polypeptide A) phosphatase, subunit 1.”
CTDP1 is the gene's official symbol. The CTDP1 gene is also known by other names, listed below.
Read more about gene names and symbols on the About page.
What is the normal function of the CTDP1 gene?
The CTDP1 gene provides instructions for making a protein called carboxy-terminal domain phosphatase 1. This protein helps regulate the activity of an enzyme called RNA polymerase II. The RNA polymerase II enzyme initiates transcription, which is a key step in using the information carried by genes to direct the production (synthesis) of proteins.
Does the CTDP1 gene share characteristics with other genes?
The CTDP1 gene belongs to a family of genes called serine/threonine phosphatases (serine/threonine phosphatases).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.
