Recombinant Human Cohesin subunit SA-1 (STAG1), Truncated

Uniprot Id

Q8WVM7

Target Species

Human

Target Name

STAG1

Target Full Name

Cohesin subunit SA-1

Target Function

Component of cohesin complex, a complex 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 cohesin complex may also play a role in spindle pole assembly during mitosis.

Target Involvement

Mental retardation, autosomal dominant 47 (MRD47)

Target Subcellular Location

Nucleus. Chromosome. Chromosome, centromere. Note=Associates with chromatin. Before prophase it is scattered along chromosome arms. During prophase, most of cohesin complexes dissociate from chromatin probably because of phosphorylation by PLK1, except at centromeres, where cohesin complexes remain. At anaphase, the RAD21 subunit of cohesin is cleaved, leading to the dissociation of the complex from chromosomes, allowing chromosome separation.

Target Protein Families

SCC3 family

Target Synonyms

Cohesin subunit SA 1; Cohesin subunit SA-1; Cohesin Subunit SA1; Nuclear protein stromal antigen 1; SA 1; SCC 3 homolog 1; Scc3; SCC3 homolog 1; STAG 1; stag1; STAG1_HUMAN; Stromal antigen 1

Target Background

This gene is a member of the SCC3 family and is expressed in the nucleus. It encodes a component of cohesin, a multisubunit protein complex that provides sister chromatid cohesion along the length of a chromosome from DNA replication through prophase and prometaphase, after which it is dissociated in preparation for segregation during anaphase.
