Summaries for SMC1B Gene

Entrez Gene Summary for SMC1B Gene

  • SMC1L2 belongs to a family of proteins required for chromatid cohesion and DNA recombination during meiosis and mitosis (3:Revenkova et al., 2001 [PubMed 11564881]).[supplied by OMIM, Mar 2008]

GeneCards Summary for SMC1B Gene

SMC1B (Structural Maintenance Of Chromosomes 1B) is a Protein Coding gene. Among its related pathways are Cell cycle and Cell Cycle, Mitotic. An important paralog of this gene is SMC1A.

UniProtKB/Swiss-Prot for SMC1B Gene

  • Meiosis-specific component of cohesin complex. Required for the maintenance of meiotic cohesion, but not, or only to a minor extent, for its establishment. Contributes to axial element (AE) formation and the organization of chromatin loops along the AE. Plays a key role in synapsis, recombination and chromosome movements. The cohesin complex is required for the cohesion of sister chromatids after DNA replication. The cohesin complex apparently forms a large proteinaceous ring within which sister chromatids can be trapped. At anaphase, the complex is cleaved and dissociates from chromatin, allowing sister chromatids to segregate. The meiosis-specific cohesin complex probably replaces mitosis specific cohesin complex when it dissociates from chromatin during prophase I (By similarity).

UniProtKB/Swiss-Prot:

SMC1B_HUMAN :
  • The flexible hinge domain, which separates the large intramolecular coiled coil regions, allows the heterotypic interaction with the corresponding domain of SMC3, forming a V-shaped heterodimer. The two heads of the heterodimer are then connected by different ends of the cleavable RAD21 or REC8 protein, forming a ring structure (By similarity).
  • Belongs to the SMC family. SMC1 subfamily.

Localization for SMC1B Gene

Subcellular locations from UniProtKB/Swiss-Prot for SMC1B Gene

Nucleus. Chromosome. Chromosome, centromere. Note=Associates with chromatin. In prophase I stage of meiosis, localizes along the AE of synaptonemal complexes. In late-pachytene-diplotene, the bulk of protein dissociates from the chromosome arms probably because of phosphorylation by PLK, except at centromeres, where cohesin complexes remain. Remains chromatin associated at the centromeres up to metaphase II. At anaphase II, dissociates from centromeres, allowing chromosomes segregation (By similarity). {ECO:0000250}.
