Protein Information
Name TAF4B
Synonyms TAF2C2, TAFII105
Function Cell type-specific subunit of the general transcription factor TFIID that may function as a gene-selective coactivator in certain cells. TFIID is a multimeric protein complex that plays a central role in mediating promoter responses to various activators and repressors. TAF4B is a transcriptional coactivator of the p65/RELA NF-kappa-B subunit. Involved in the activation of a subset of antiapoptotic genes including TNFAIP3. May be involved in regulating folliculogenesis. Through interaction with OCBA/POU2AF1, acts as a coactivator of B-cell-specific transcription. Plays a role in spermiogenesis and oogenesis.
Cellular Location Nucleus. Cytoplasm Note=Export into the cytoplasm is mediated by a CRM1-independent nuclear export pathway and not by phosphorylation
Tissue Location Preferentially expressed in ovarian granulosa cells (at protein level). Highly expressed in B-cells
