Gene Snapshot

Gene Group (FlyBase)

E2 UBIQUITIN CONJUGATING ENZYMES -: Ubiquitin-conjugating (E2) enzymes accept activated ubiquitin from ubiquitin-activating (E1) enzymes via thioester bond with a conserved catalytic cysteine. E2s then interact with ubiquitin ligases (E3) to directly or indirectly ubiquitinate target proteins. E2s are characterised by a 200 amino acid ubiquitin-conjugating (UBC) domain which interacts with E1 and E3s and acts catalytically. (Adapted from PMID:1994026).
ATYPICAL PROTEIN KINASES -: Atypical kinases are protein kinases or putative protein kinases that do not share clear sequence similarity with conventional eukaryotic protein kinases, but they or their orthologs have been shown experimentally to have protein kinase activity. Atypical kinases are defined in FBrf0201870.
TRANSCRIPTION FACTOR II D -: The general transcription factor complex Transcription factor II D (TFIID) plays an important role in recruiting the transcription machinery to core promoters. TFIID is a complex composed of TBP and several TBP-associated factors. (Adapted from FBrf0125116 and FBrf0156065).
UBIQUITIN ACTIVATING ENZYMES -: Ubiquitin activating enzymes are 'canonical' E1 enzymes that activate ubiquitin for subsequent steps along the ubiquitin conjugation cascade. They perform three distinct chemical reactions: first, they bind ATP, magnesium and ubiquitin to catalyze formation of a high-energy acyl adenylate intermediate with subsequent release of pyrophosphate; second, an E1 catalytic cysteine attacks the ubiquitin-adenylate to catalyze formation of a high-energy thioester bond between the E1 and ubiquitin and release of the AMP product; finally, the E1-ubiquitin catalyzes transthioesterification to an E2 to form a high energy thioester-linked E2-ubiquitin product. (Adapted from PMID:28234446.)
HISTONE ACETYLTRANSFERASES -: Histone acetyltransferases catalyze the acetylation of conserved lysine residues on histone proteins by transferring an acetyl group from acetyl CoA to form ε-N-acetyl lysine. (Adapted from PMID:11395403).

Protein Function (UniProtKB)

TFIID is a multimeric protein complex that plays a central role in mediating promoter responses to various activators and repressors. Largest component and core scaffold of the complex. Contains N- and C-terminal Ser/Thr kinase domains which can autophosphorylate or transphosphorylate other transcription factors. Possesses DNA-binding activity. Essential for progression of the G1 phase of the cell cycle. Negative regulator of the TATA box-binding activity of Tbp.

Additional Descriptive Data

Taf1 protein is first detected in mitotically profliferating spermatogonia at the apical tip of the testis. Taf1 levels increases in spermatocytes and reaches the highest levels in nuclei of spermatocytes undergoing growth in an extended pre-meiotic G2 phase. Upon entry into meiosis, expression is reduced and the Taf1 protein is dispersed throughout the cell. @Taf1 is dynamically localized within the nucleus during spermatogenesis and predominantly localizes to spermatocyte nucleoli.

Additional comments

Other Comments

dsRNA has been made from templates generated with primers directed against this gene.

(Marr et al., 2006)

The proteins encoded by Tbp, Taf1, Taf2 and Taf11 are likely peripheral subunits of TFIID.

(Wright et al., 2006)

The proteins encoded by Taf1 and Taf4 have a specific role in transcription activation from TATA-less, downstream core promoter element (DPE)-containing promoters.

(Wright et al., 2006)

When dsRNA constructs are made and transiently transfected into S2 cells in RNAi experiments, an increase in the proportion of S phase cells, an increase in the proportion of G2/M phase cells, a decrease in mitotic index and a whole range of mitotic abnormalities are seen.

(Bettencourt-Dias et al., 2004)

Taf1 is a histone specific ubiquitin activating/conjugating enzyme (ubac).

(Pham and Sauer, 2000)

Taf1 is required in ovary, eye, ocelli, wing bristle and terminalia development and has a suggested role in regulating the cell cycle, cell differentiation, cell proliferation and cell survival.

(Wassarman et al., 2000)

Transcriptional regulation may involve, in part, competitive interactions between transcriptional activators and TAFs on the Tbp surface.

(Nishikawa et al., 1997)

Identified on the basis of genetic interaction with Ras85D^V12.sev.

(Karim et al., 1996)

Taf1 exhibits histone acetyltransferase (HAT) activity in vitro.

(Mizzen et al., 1996)

A quadruple complex containing Tbp, Taf1, Taf4 and Taf6 mediates transcriptional synergism by bcd and hb, whereas triple Tbp-Taf complexes lacking one or other coactivator failed to support synergistic activation. The concerted action of multiple regulators with different coactivators helps to establish the pattern and level of segmentation gene transcription during development.

(Sauer et al., 1995)

The assembly and purification of various functional Tbp TAF complexes demonstrate that Tbp plus the TAFs is sufficient to replace endogenous TFIID to support activated transcription in vitro.

(Chen et al., 1994)

TFIID subunit proteins and the Tbp protein can interact in pairwise combinations with several subunits in a network of interactions within TFIID.

(Kokubo et al., 1994)

N terminal sites of Taf1 mediate strong physical interaction with Tbp and inhibit Tbp function. Interaction of the N terminal region with Tbp may directly control TATA-box binding.

(Kokubo et al., 1994)

Taf1 contains at least two sites of interaction with Tbp.

(Kokubo et al., 1994)

Purified Taf5 is unable to bind Tbp directly or to interact strongly with the C-terminal domain of Taf1, but can only interact with a complex containing Tbp, Taf1, Taf4 and Taf6.

(Dynlacht et al., 1993)

Taf1 gene product interacts directly with Tbp.

(Kokubo et al., 1993)

A number of polypeptides (encoded by Taf1, Taf4, Taf5, Taf6, e(y)1 and Taf12) that are tightly associated with Tbp and are native TFIID components have been purified. Protein blotting experiments suggest that one of these proteins, Taf1, interacts directly with Tbp, while the association between Tbp and the other proteins is either weak or is an indirect association via Taf1.

(Kokubo et al., 1993)

In vitro expressed 'TAF110' interacts directly with the 'TAF250' which itself interacts with Tbp, a complex of all three is suggested. Binding study with various mutants of Taf1 suggests that both 'TAF110' and Tbp interact with the N-terminal 352-amino acid portion of 'TAF250'.

(Kokubo et al., 1993)

The Taf6 product interacts directly with Taf1 in vitro.

(Weinzierl et al., 1993)

Tbp, Taf1, Taf4 and Taf6 products can assemble into a mini-complex in vitro, showing that Taf6 and Taf4 occupy distinct binding sites on the C terminal part of Taf1.

(Weinzierl et al., 1993)

The assembly of a partial complex containing recombinant Tbf1, Taf1 and Taf4 was reported. This triple complex supports activation of HeLa cell Sp1 and reveals specific interactions between Tbp, Taf1 and Taf4.
