microcephalin isoform 8 [Homo sapiens]

Protein Classification

BRCT domain-containing protein( domain architecture ID 13026451)

BRCT (BRCA1 C-terminus) domain-containing protein may interact with DNA, and participate in DNA-damage checkpoint or DNA-repair pathways; similar to vertebrate microcephalin implicated in chromosome condensation and DNA damage induced cellular responses

Microcephalin protein; This family of proteins is found in eukaryotes. Proteins in this family are typically between 384 and 835 amino acids in length. Microcephalin is involved in determining the size of the brain in animals. It is a protein, which if expressed homozygously causes the organizm to have the condition microcephaly. organizms expressing the mutated form of this protein in a homozygous manner develop a condition called microcephaly - a drastically reduced brain mass and volume. Microcephalin is predicted to contain three BRCA1 C-terminal domains, the first of which is the probable microcephaly mutation site.

BRCT domain, a BRCA1 C-terminus domain; This BRCT domain, a BRCA1 C-terminus region, is found on many RAP1 proteins, usually at the very N-terminus. The function in human at least of a BRCT is to contribute to the heterogeneity of the telomere DNA length, but that may not be its general function, which remains unknown.

 18-79 1.42e-08

C-terminal domain of the breast cancer suppressor protein (BRCA1) and related domains; The BRCT (BRCA1 C-terminus) domain is found within many DNA damage repair and cell cycle checkpoint proteins. BRCT domains interact with each other forming homo/hetero BRCT multimers, but are also involved in BRCT-non-BRCT interactions and interactions within DNA strand breaks. BRCT tandem repeats bind to phosphopeptides; it has been shown that the repeats in human BRCA1 bind specifically to pS-X-X-F motifs, mediating the interaction between BRCA1 and the DNA helicase BACH1, or BRCA1 and CtIP, a transcriptional corepressor. It is assumed that BRCT repeats play similar roles in many signaling pathways associated with the response to DNA damage.

BRCT domain, a BRCA1 C-terminus domain; This BRCT domain, a BRCA1 C-terminus region, is found on many RAP1 proteins, usually at the very N-terminus. The function in human at least of a BRCT is to contribute to the heterogeneity of the telomere DNA length, but that may not be its general function, which remains unknown.

BRCA1 C Terminus (BRCT) domain; The BRCT domain is found predominantly in proteins involved in cell cycle checkpoint functions responsive to DNA damage. The BRCT domain of XRCC1 forms a homodimer in the crystal structure. This suggests that pairs of BRCT domains associate as homo- or heterodimers. BRCT domains are often found as tandem-repeat pairs. Structures of the BRCA1 BRCT domains revealed a basis for a widely utilized head-to-tail BRCT-BRCT oligomerization mode. This conserved tandem BRCT architecture facilitates formation of the canonical BRCT phospho-peptide interaction cleft at a groove between the BRCT domains. Disease associated missense and nonsense mutations in the BRCA1 BRCT domains disrupt peptide binding by directly occluding this peptide binding groove, or by disrupting key conserved BRCT core folding determinants.

BRCT domain of RNA polymerase II subunit A C-terminal domain phosphatase (CTDP1) and similar proteins; CTDP1 (EC 3.1.3.16), also termed TFIIF-associating CTD phosphatase, or TFIIF- associating RNA polymerase C-terminal domain phosphatase (FCP1), promotes the activity of RNA polymerase II through processively dephosphorylating 'Ser-2' and 'Ser-5' of the heptad repeats YSPTSPS in the C-terminal domain of the largest RNA polymerase II subunit. It plays a role in the exit from mitosis by dephosphorylating crucial mitotic substrates (USP44, CDC20 and WEE1) that are required for M-phase-promoting factor (MPF)/CDK1 inactivation.

second (C-terminal) BRCT domain of breast cancer type 1 susceptibility protein (BRCA1) and similar proteins; BRCA1, also termed RING finger protein 53 (RNF53), is a RING finger protein encoded by BRCA1, a tumor suppressor gene that regulates all DNA double-strand break (DSB) repair pathways. BRCA1 is frequently mutated in patients with hereditary breast and ovarian cancer (HBOC). Its mutation is also associated with an increased risk of pancreatic, stomach, laryngeal, fallopian tube, and prostate cancer. It plays an important role in the DNA damage response signaling, and has been implicated in various cellular processes such as cell cycle regulation, transcriptional regulation, chromatin remodeling, DNA DSBs, and apoptosis. BRCA1 contains an N-terminal C3HC4-type RING-HC finger, and two BRCT repeats at the C-terminus. The family corresponds to the second BRCT domain.
