Summary

SMC1A (structural maintenance of chromosomes 1A, HGNC:11111) is a protein-coding gene on chromosome Xp11.22, encoding Structural maintenance of chromosomes protein 1A (Q14683). Involved in chromosome cohesion during cell cycle and in DNA repair. It is a common-essential gene (DepMap: required in 98.9% of cancer cell lines) and haploinsufficient (ClinGen: sufficient evidence).

Proper cohesion of sister chromatids is a prerequisite for the correct segregation of chromosomes during cell division. The cohesin multiprotein complex is required for sister chromatid cohesion. This complex is composed partly of two structural maintenance of chromosomes (SMC) proteins, SMC3 and either SMC1B or the protein encoded by this gene. Most of the cohesin complexes dissociate from the chromosomes before mitosis, although those complexes at the kinetochore remain. Therefore, the encoded protein is thought to be an important part of functional kinetochores. In addition, this protein interacts with BRCA1 and is phosphorylated by ATM, indicating a potential role for this protein in DNA repair. This gene, which belongs to the SMC gene family, is located in an area of the X-chromosome that escapes X inactivation. Mutations in this gene result in Cornelia de Lange syndrome. Alternative splicing results in multiple transcript variants encoding different isoforms.

Function. Involved in chromosome cohesion during cell cycle and in DNA repair. Central component of cohesin complex. 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 cohesin complex may also play a role in spindle pole assembly during mitosis. Involved in DNA repair via its interaction with BRCA1 and its related phosphorylation by ATM, or via its phosphorylation by ATR. Works as a downstream effector both in the ATM/NBS1 branch and in the ATR/MSH2 branch of S-phase checkpoint.

Subunit / interactions. Forms a heterodimer with SMC3 in cohesin complexes. Cohesin complexes are composed of the SMC1 (SMC1A or SMC1B) and SMC3 heterodimer attached via their SMC hinge domain, RAD21 which link them, and one STAG protein (STAG1, STAG2 or STAG3), which interacts with RAD21. In germ cell cohesin complexes, SMC1A is mutually exclusive with SMC1B. Interacts with BRCA1. Found in a complex with CDCA5, SMC3 and RAD21, PDS5A/SCC-112 and PDS5B/APRIN. Interacts with NDC80. Interacts with BRAT1. Found in a complex containing POLE and SMC3. Interacts with RPGR, STAG3 and SYCP2. The cohesin complex interacts with the cohesin loading complex subunits NIPBL/Scc2 (via HEAT repeats) and MAU2/Scc4. NIPBL directly contacts all members of the complex, RAD21, SMC1A/B, SMC3 and STAG1.

Subcellular location. Nucleus. Chromosome. Centromere. Kinetochore.

Post-translational modifications. Ubiquitinated by the DCX(DCAF15) complex, leading to its degradation. Phosphorylated by ATM upon ionizing radiation in a NBS1-dependent manner. Phosphorylated by ATR upon DNA methylation in a MSH2/MSH6-dependent manner. Phosphorylation of Ser-957 and Ser-966 activates it and is required for S-phase checkpoint activation.

Disease relevance. Cornelia de Lange syndrome 2 (CDLS2) [MIM:300590] A form of Cornelia de Lange syndrome, a clinically heterogeneous developmental disorder associated with malformations affecting multiple systems. Characterized by facial dysmorphisms, abnormal hands and feet, growth delay, cognitive retardation, hirsutism, gastroesophageal dysfunction and cardiac, ophthalmologic and genitourinary anomalies. The disease is caused by variants affecting the gene represented in this entry. Developmental and epileptic encephalopathy 85 with or without midline brain defects (DEE85) [MIM:301044] An X-linked form of epileptic encephalopathy, a heterogeneous group of severe early-onset epilepsies characterized by refractory seizures, neurodevelopmental impairment, and poor prognosis. Development is normal prior to seizure onset, after which cognitive and motor delays become apparent. DEE85 is characterized by onset of severe refractory seizures in the first year of life, global developmental delay with impaired intellectual development and poor or absent speech, and dysmorphic facial features. Many patients have midline brain defects on brain imaging. The disease is caused by variants affecting the gene represented in this entry.

Domain organisation. The flexible SMC 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 protein, forming a ring structure.

Miscellaneous. Mutated Cornelia de Lange cell lines display genomic instability and sensitivity to ionizing radiation and interstrand cross-linking agents.

Similarity. Belongs to the SMC family. SMC1 subfamily.

Enriched among interaction partners

Reactome pathways and GO biological processes over-represented among this gene’s 175 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
