Structural maintenance of chromosomes 3, also known as SMC3, is a human gene.[5]

Function

This gene belongs to the SMC3 subfamily of SMC proteins. The encoded protein occurs in certain cell types as either an intracellular, nuclear protein or a secreted protein. The nuclear form, known as structural maintenance of chromosomes 3, is a component of the multimeric cohesin complex that holds together sister chromatids during mitosis, enabling proper chromosome segregation. Post-translational modification of the encoded protein by the addition of chondroitin sulfate chains gives rise to the secreted proteoglycan bamacan, an abundant basement membrane protein.[5]

Model organisms

Model organisms have been used in the study of SMC3 function. A conditional knockout mouse line, called Smc3tm1a(EUCOMM)Wtsi[13][14] was generated as part of the International Knockout Mouse Consortium program — a high-throughput mutagenesis project to generate and distribute animal models of disease to interested scientists.[15][16][17]

Male and female animals underwent a standardized phenotypic screen to determine the effects of deletion.[11][18] Twenty two tests were carried out on mutant mice and six significant abnormalities were observed.[11] No homozygous mutant embryos were identified during gestation, and thus none survived until weaning. The remaining tests were carried out on heterozygous mutant adult mice. Females had a higher than normal incidence of pre-wean death in their offspring, and also had a decreased body weight. Males heterozygotes displayed a shortened, upturned snout.[11][18]
