 55-128 7.34e-46

histone-fold domain found in transcription initiation factor TFIID subunit 12 (TAF12) and similar proteins; TAF12, also called TATA Binding Protein (TBP) associated factor 12, transcription initiation factor TFIID 20/15 kDa subunits, TAFII-20/TAFII-15, or TAFII20/TAFII15, is a TBP-associated factor (TAF). TAFs are components of the transcription factor IID (TFIID) complex, PCAF histone acetylase complex, and TBP-free TAFII complex (TFTC). TIIFD is multimeric protein complex that plays a central role in mediating promoter responses to various activators and repressors. TFIID and PCAF are composed of TATA binding protein (TBP) and several TAFs. TBP is not part of TFTC. TAFs are essential for mediating regulation of RNA polymerase transcription. TAF12 interacts with TAF4 and makes a novel histone-like heterodimer that binds DNA and has a core promoter function of a subset of genes. It is important for RAS-induced transformation properties of human colorectal cancer cells; its levels are increased in the cells harboring the RAS mutation. Also, TAF12 interacts with activating transcription factor 7 (ATF7) and contributes to the hypersensitivity of osteoclast (OCL) precursors to 1,25-dihydroxyvitamin D2 (1,25-(OH)2D3; also known as calcitriol) in Paget's disease (PD), a disorder of the bone remodeling process, in which the body absorbs old bone and forms abnormal new bone.

 58-121 8.22e-05

histone fold domain (HFD) superfamily; The histone fold domain (HFD) is a structurally conserved interaction motif involved in heterodimerization of the core histones and their assembly into the nucleosome octamer. Histone fold heterodimers play crucial roles in gene regulation. The minimal HFD consists of three alpha helices connected by two short, unstructured loops. The HFD is found in core histones, TATA box-binding protein-associated factors (TAFs), and many other transcription factors. HFD plays a role in the nucleosomal core particle by conserving histone interactions; these contain more than one HFD. The structure of the nucleosome core particle has two modes that have the largest interaction surfaces, and these are the H3-H4 and H2A-H2B heterodimer interactions. Several TAFs interact via histone-fold (HF) motifs. Five HF-containing TAF pairs have been described in transcription factor II D (TFIID): TAF6-TAF9, TAF4-TAF12, TAF11-TAF13, TAF8-TAF10 and TAF3-TAF10.

 73-123 4.16e-04

histone-fold domain found in centromere protein T (CENP-T) and similar proteins; CENP-T, also called interphase centromere complex protein 22 (ICEN22), is a component of the CENPA-NAC (nucleosome-associated) complex, which plays a central role in the assembly of kinetochore proteins, mitotic progression, and chromosome segregation. The CENPA-NAC complex recruits the CENPA-CAD (nucleosome distal) complex and may be involved in incorporation of newly synthesized CENPA into centromeres. CENP-T is also part of a nucleosome-associated complex that binds specifically to histone H3-containing nucleosomes at the centromere, as opposed to nucleosomes containing CENPA. Moreover, CENP-T is a component of the heterotetrameric CENP-T-W-S-X complex that binds and supercoils DNA, and plays an important role in kinetochore assembly. CENP-T has a fundamental role in kinetochore assembly and function. It is one of the inner kinetochore proteins, with most further proteins binding downstream. It is required for normal chromosome organization and normal progress through mitosis.
