Gene: SMC1A (structural maintenance of chromosomes 1A) Homo sapiens
Symbol: SMC1A
Name: structural maintenance of chromosomes 1A
Description: Exhibits chromatin binding activity and protein heterodimerization activity. Involved in several processes, including regulation of mitotic spindle assembly; response to DNA damage checkpoint signaling; and sister chromatid cohesion. Localizes to several cellular components, including the chromosome; mitotic spindle pole; and nuclear lumen. Implicated in Cornelia de Lange syndrome 2.
Type: protein-coding
RefSeq Status: REVIEWED
