|Application ||WB, FC, E|
|Other Accession||G5E8Z2, NP_005631.1|
|Calculated MW||91091 Da|
|Antigen Region||647-675 aa|
|Other Names||Transcription initiation factor TFIID subunit 4B, Transcription initiation factor TFIID 105 kDa subunit, TAF(II)105, TAFII-105, TAFII105, TAF4B, TAF2C2, TAFII105|
|Target/Specificity||This TAF4B antibody is generated from rabbits immunized with a KLH conjugated synthetic peptide between 647-675 amino acids from the C-terminal region of human TAF4B.|
|Format||Purified polyclonal antibody supplied in PBS with 0.09% (W/V) sodium azide. This antibody is purified through a protein A column, followed by peptide affinity purification.|
|Storage||Maintain refrigerated at 2-8°C for up to 2 weeks. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles.|
|Precautions||TAF4B Antibody (C-term) is for research use only and not for use in diagnostic or therapeutic procedures.|
|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|

TATA-binding protein associated factors (TAFs) participate, with TATA binding protein (TBP; MIM 600075), in the formation of the TFIID protein complex (see MIM 313650), which is involved in the initiation of gene transcription by RNA polymerase II (see MIM 180660).
