 169-257 8.36e-27

Middle HEAT-repeat binding domain found in Homo sapiens nuclear matrix protein 1 (NXP-1) and similar proteins; NXP-1, also called double-strand-break repair protein Rad21 homolog (HR21), or Scc1 homolog, is related to Rad21/Scc1/Mcd1. As a component of the cohesin complex, it is involved in sister chromatid cohesion from the time of DNA replication in S phase to their segregation in mitosis, a function that is essential for proper chromosome segregation, post-replicative DNA repair, and the prevention of inappropriate recombination between repetitive regions. The cohesin complex may also play a role in spindle pole assembly during mitosis. The family also includes double-strand-break repair protein rad21-like protein 1 (RAD21L), which is a meiosis-specific component of some cohesin complex required during the initial steps of prophase I in male meiosis. This model corresponds to the HEAT-repeat binding domain of NXP-1 located in the middle/central region, which consists of four short helices and two long extended segments. It is responsible for the binding of cohesin HEAT-repeat subunit SA2. The SA2:NXP-1 heterodimer mediates the binding between cohesin and its regulators, including Scc2-Scc4, Pds5, Wapl, and Sgo1.

 389-440 1.86e-15

Conserved region of Rad21 / Rec8 like protein; This family represents a conserved region found in eukaryotic cohesins of the Rad21, Rec8 and Scc1 families. Members of this family mediate sister chromatid cohesion during mitosis and meiosis, as part of the cohesin complex. Cohesion is necessary for homologous recombination (including double-strand break repair) and correct chromatid segregation. These proteins may also be involved in chromosome condensation. Dissociation at the metaphase to anaphase transition causes loss of cohesion and chromatid segregation.

Middle HEAT-repeat binding domain of Rad21/Rec8-like proteins; This family includes eukaryotic cohesins of the Rad21, Rec8, and Scc1 subfamilies. They mediate sister chromatid cohesion during mitosis and meiosis, as part of the cohesin complex. Cohesion is necessary for homologous recombination (including double-strand break repair) and correct chromatid segregation. These proteins may also be involved in chromosome condensation. Dissociation at the metaphase to anaphase transition causes loss of cohesion and chromatid segregation. This model corresponds to a conserved middle/central region of family members, consisting of short helices and two extended segments, which functions in binding to HEAT-repeat containing cohesin subunits. For example, human Scc1 homolog (NXP-1) binds to either SA1 or SA2, two homologous HEAT-containing proteins; the SA-Scc1 heterodimer mediates the binding between cohesin and its regulators, including Scc2-Scc4, Pds5, Wapl, and Sgo1.

Middle HEAT-repeat binding domain found in Schizosaccharomyces pombe cohesin subunit rad21 ...
 170-254 2.64e-05

Middle HEAT-repeat binding domain found in Schizosaccharomyces pombe cohesin subunit rad21 (SpRad21p) and similar proteins; SpRad21p, also called double-strand-break (DSB) repair protein rad21, or SCC1 homolog, is a cleavable component of the cohesin complex, involved in chromosome cohesion during the cell cycle. The cohesin complex is required for the cohesion of sister chromatids after DNA replication. It apparently forms a large proteinaceous ring within which sister chromatids can be trapped. At the metaphase-anaphase transition, SpRad21p is cleaved by cut1 and dissociates from chromatin, allowing sister chromatids to segregate. It is also involved in the DNA DSB repair system. This model corresponds to a small region in the middle of SpRad21p that shows high sequence similarity with the HEAT-repeat binding domain found in both Saccharomyces cerevisiae sister chromatid cohesion protein 1 (ScScc1p) and Homo sapiens nuclear matrix protein 1 (NXP-1), which consists of short helices and two long extended segments.
