Research Backgrounds
Part of the TFIID complex, a multimeric protein complex that plays a central role in mediating promoter responses to various activators and repressors. Potentiates transcriptional activation by the AF-2S of the retinoic acid, vitamin D3 and thyroid hormone.
Nucleus.
TFIID is composed of TATA binding protein (TBP) and a number of TBP-associated factors (TAFs). Component of the TFTC-HAT complex, at least composed of TAF5L, TAF6L, TADA3L, SUPT3H, TAF2, TAF4, TAF5, GCN5L2/GCN5, TAF10 and TRRAP. Component of some MLL1/MLL complex, at least composed of the core components KMT2A/MLL1, ASH2L, HCFC1/HCF1, WDR5 and RBBP5, as well as the facultative components BAP18, CHD8, E2F6, HSP70, INO80C, KANSL1, LAS1L, MAX, MCRS1, MGA, MYST1/MOF, PELP1, PHF20, PRP31, RING2, RUVB1/TIP49A, RUVB2/TIP49B, SENP3, TAF1, TAF4, TAF6, TAF7, TAF9 and TEX10. Interacts with ATF7; the interaction inhibits ATF7-mediated tranactivation.
(Microbial infection) Interacts with SV40 Large T antigen.
Belongs to the TAF4 family.
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.
Under stimulation by forskolin, Isoform 1 is phosphorylated by protein kinase A (PKA).
Nucleus. Cytoplasm.
Note: Export into the cytoplasm is mediated by a CRM1-independent nuclear export pathway and not by phosphorylation.
Preferentially expressed in ovarian granulosa cells (at protein level). Highly expressed in B-cells.
TFIID is composed of TATA binding protein (TBP) and a number of TBP-associated factors (TAFs). Heterodimerizes with TAF12/TFII20 via the C-terminal H2A-like histone-fold domain. This heterodimer forms a histone-like octamer with the TAF6/TAFII70-TAF9/TAFII31 heterodimer. Interacts with P65/RELA homodimers and P65/RELA-REL heterodimers. Interaction with POU2AF1, via its C-terminal activation domain, is required for octamer-dependent transcription.
Belongs to the TAF4 family.
