TAFs are components of the transcription factor IID (TFIID) complex that is essential for mediating regulation of RNA polymerase transcription. Involved in osmotic stress adaptation during the germination stage and in gene expression related to meristem activity and leaf development. Component of the TFIID complex. TFIID is composed of TATA binding protein (TBP) and a number of TBP-associated factors (TAFs) whose MWs range from 14-217 kDa. Can homodimerize. Interacts with TAF4, TAF4B, TAF8, TAF9, TAF12B and TAF13. Expressed in roots, stems, leaves and inflorescences. Expressed preferentially in the vascular bundles and bundle sheath cells of cotyledons, the phloem of hypocotyls and the central cylinders of roots. Expressed transiently during the development of several organs such as lateral roots, rosette leaves and most floral organs. Up-regulated by auxin and cytokinin. Overexpression of TAF10 results in salt tolerance during seed germination while knock-down mutants are more sensitive to osmotic stress (PubMed:16945932) and display several abnormal phenotypes involved in meristem activity and leaf development (PubMed:17148695). Belongs to the TAF10 family.
