Western Blot Shows Human TAF15 Specificity Using Knockout Cell Line.

Western blot shows lysates of HAP1 human near-haploid cell line and TAF15 knockout HAP1 cell line (KO). Nitrocellulose membrane was probed with TAF15 Antibody (Catalog # NBP1-92685) O/N at 4C, followed by HRP-conjugated Secondary Antibody and ECL detection. A specific band was detected for TAF15 (75 kDa) in the parental HAP1 cell line, but is not detectable in knockout HAP1 cell line. Primary antibody dilution used: 1/1000. The Ponceau stained transfers of each blot are shown. Image, protocol and testing courtesy of YCharOS Inc. (ycharos.com).

Immunocytochemistry/Immunofluorescence: TAF15 Antibody (4D71) [NBP1-92685] - Analysis of HeLa cells stained with mouse mAb to TATA-box binding protein associated factor 15, TAF15, NBP1-92685, dilution 1:500 in red, and costained with rabbit pAb to GAPDH, dilution 1:1,000 in green. Blue is Hoechst staining of nuclear DNA. The NBP1-92685 antibody reveals TAF15 protein expressed exclusively in the nuclei of the cells, while GAPDH antibody produces strong cytoplasmic staining.

Background: TAF15

TAF15 (TAF2N or TAFII68) is a nuclear protein known to associate with a distinct subpopulation of transcription factor IID (TFIID), a multi-subunit complex that nucleates the pre-initiation complex on promoters of on protein-coding genes. TAF15 harbors a transcriptional activation domain, a RNA recognition motif and many Arg-Gly-Gly repeats that participate in RNA binding. TAF15 along with FUS and EWS constitutes the FET (FUS/EWS/TAF15) protein family of heterogeneous nuclear ribonucleoproteins (hnRNPs) class of RNA binding proteins that are multifunctional proteins implicated in numerous aspects of RNA processing/functions. TAF15 is a nuclear protein that shuttle between cytoplasm-nucleus and as RNA/ssDNA-binding protein, it play specific roles during transcription initiation at distinct promoters and enter the preinitiation complex together with the RNA polymerase II. TAF15 as well as other FET member genes are frequently translocated in sarcomas and rare hematopoietic as well as epithelial cancers. Moreover, dominant mutations in genes coding for four hnRNPs (TDP-43, FUS/TLS, TAF15, and EWS) are found in familial and sporadic cases of ALS and a chromosomal aberration involving TAF15/TAF2N is found in a form of extraskeletal myxoid chondrosarcomas (EMC).
