25080505 The SMC1a mutation leads to chromosomal instability and tumorigenesis in early colorectal adenomas.
24756084 A dominant negative effect is considered the pathogenic mechanism in SMC1A-defective female patients, the level of allelic preferential expression might be one of the factors contributing to the wide phenotypic variability observed in these patients.
24124034 Our clinical and molecular findings expand the total number of characterized SMC1A-mutated patients (from 44 to 52) and the restricted repertoire of SMC1A mutations (from 29 to 34), contributing to the molecular and clinical signature of SMC1A-based CdLS.
23863341 The mutation c.1731G>A/p.E577E in our patient expands the mutational spectrum of SMC1A to splice site mutations and also represents the first exonic synonymous splice site mutation observed in any human cohesinopathy
23776448 Human SMC3 knock-down rendered SMC1 instable without cytoplasmic accumulation.
23754617 Inhibiting SMC1A expression efficiently (P < 0.001) resulted in inhibiting the proliferation and colony formation of U251 and U87MG glioblastoma cells.
23717600 studies report for the first time that SMC1 is overexpressed in TNBC cells where it plays a role in cell migration and drug sensitivity, and thus provides a potential therapeutic target for this highly invasive breast cancer subtype
23683030 Clinical comparison between our patient with a previously reported individual with a SMC1A duplication and four male carriers of similar sSMC reported in databases, suggest that they all share clinical features related to cohesinopathies

20016259 Interaction between Rae1 and cohesin subunit SMC1 is required for proper spindle formation.
19701948 results suggest that mechanistically SMC1A-related Cornelia de Lange Syndrome is not due to altered levels of the SMC1A transcript, but rather that the mutant proteins maintain a residual function in males and enact a dominant negative effect in females.
19468298 Transcription in severely affected Cornelia de Lange Syndrome probands has identified a unique profile of dysregulated gene expression that correlates with phenotypic severity and SMC1A binding analysis demonstrates a preference for intergenic regions.
19414588 SMC1, a substrate of ATM, could not be phosphorylated at the DNA damage sites in the absence of PTIP
19052029 This study identified duplications Cornelia de Lange syndrome (CdLS) on chromosomes 5 or X using genome wide array comparative genomic hybridisation (aCGH). The duplicated regions contain either the NIPBL or the SMC1A genes.

17102637 nuclear exclusion is important to prevent cohesin cleavage during interphase in the absence of securin and the phosphorylation inhibition
16623664 SMC1 binding represses OARE [OA (okadaic acid) response element] activity and its dissociation allows the recruitment of CAR(constitutive active/androstane receptor) to the OARE, synergizing the expression of the CYP2B6 gene.
