TBP-associated factor 2N; RNA-binding protein 56; RBP56; TAF15 RNA polymerase 2; TATA box-binding protein-associated factor 68-kd (TAF2N)

Function: - RNA & ssDNA-binding protein that may play specific roles during transcription initiation at distinct promoters - can enter the preinitiation complex together with the RNA polymerase 2 - belongs to the RNA polymerase 2 transcriptional multiprotein complex, together with the TATA-binding protein (TBP) & other TBP-associated factors (TAF(II)s) - binds SF1 - Arg-206 is dimethylated, probably to asymmetric dimethylarginine - phosphorylated upon DNA damage, probably by ATM or ATR Structure: - belongs to the RRM TET family - contains 1 RanBP2-type Zn+2 finger - contains 1 RRM domain (RNA recognition motif) Compartment: nucleus (putative) Alternative splicing: named isoforms=2 Expression: - ubiquitous - observed in all fetal & adult tissues Pathology: - chromosomal translocation t(9;17)(q22;q11) involving TAF2N with NR4A3 is found in a form of extraskeletal myxoid chondrosarcoma
