General annotation (Comments)

Function

Processively dephosphorylates 'Ser-2' and 'Ser-5' of the heptad repeats YSPTSPS in the C-terminal domain of the largest RNA polymerase II subunit. This promotes the activity of RNA polymerase II.

Catalytic activity

A phosphoprotein + H2O = a protein + phosphate.

Subunit structure

Homodimer. Interacts with GTF2F1. Interacts with WDR77, SNRPB and SNRNP70. Ref.1 Ref.6

Subcellular location

Nucleus.

Tissue specificity

Ubiquitously expressed. Isoform 3 is expressed in heart, brain, placenta, lung, liver, skeletal muscle, kidney and placenta. Ref.1

Post-translational modification

Phosphorylated. In the presence of TFIIF, the phosphorylated form has an increased CTD phosphatase activity. The phosphorylation is required for the physical interaction with GTF2F1. Ref.7 Ref.8 Ref.9 Ref.10 Ref.11

Involvement in disease

Defects in CTDP1 are a cause of congenital cataracts facial dysmorphism and neuropathy syndrome (CCFDN) [MIM:604168]. CCFDN is an autosomal recessive developmental disorder that occurs in an endogamous group of Vlax Roma (Gypsies). The syndrome is characterized by a complex clinical phenotype with seemingly unrelated features involving multiple organs and systems. Developmental abnormalities include congenital cataracts and microcorneae, hypomyelination of the peripheral nervous system, impaired physical growth, delayed early motor and intellectual development, facial dysmorphism and hypogonadism. Central nervous system involvement, with cerebral and spinal cord atrophy, may be the result of disrupted development with superimposed degenerative changes. Affected individuals are prone to severe rhabdomyolysis after viral infections and to serious complications related to general anesthesia (such as pulmonary edema and epileptic seizures). Ref.15

Sequence similarities

Contains 1 BRCT domain.

Contains 1 FCP1 homology domain.

Alternative products

This entry describes 4 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: Q9Y5B0-1)

Also known as: Fcp1;

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.

Isoform 3 (identifier: Q9Y5B0-3)

Also known as: Fcp1b;

The sequence of this isoform differs from the canonical sequence as follows:
     1-119: Missing.
Isoform 4 (identifier: Q9Y5B0-4)

The sequence of this isoform differs from the canonical sequence as follows:
     807-961: AVPPPQPQMF...ALEAELNDLM → WTTSLEKAAT...AGGPEATRGS
