Protein names


Protein function

Probably functions as scaffold protein that is part of numerous complexes and thereby plays a role in pre-mRNA splicing, transcription regulation and neuron development. Required for normal alternative splicing of target pre-mRNA species . May suppress the ability of POU3F2 to transactivate the DRD1 gene in a POU3F2 dependent manner. Can activate transcription directly or via association with the transcription machinery. May be involved in ATXN1 mutant-induced cell death. The interaction with ATXN1 mutant reduces levels of phosphorylated RNA polymerase II large subunit.

Protein tissue specificity

Widely expressed with high level in heart, skeletal muscle, pancreas, spleen, thymus, prostate, ovary, small intestine and peripheral blood leukocytes.

Protein sequence and domain

The WW domain may play a role as a transcriptional activator directly or via association with the transcription machinery. The WW domain mediates interaction with WBP11, ATN1, SF3B1 and the C-terminal domain of the RNA polymerase II large subunit.; Except for the WW domain, the protein is intrinsically disordered.Contains 1 WW domain.

Protein cellular localization

Nucleus . Nucleus speckle . Note: Colocalizes with SRSF2 in nuclear speckles (By similarity). Colocalized with POU3F2. Colocalized with ATXN1 in nuclear inclusion bodies.


This gene encodes a nuclear polyglutamine-binding protein that is involved with transcription activation. The encoded protein contains a WW domain. Mutations in this gene have been found in patients with Renpenning syndrome 1 and other syndromes with X-linked mental retardation. Multiple alternatively spliced transcript variants that encode different protein isoforms have been described for this gene.
