Nipped-B-like protein (NIPBL), also known as delangin or SCC2 homolog is a protein that in humans is encoded by the NIPBL gene.^[1]

Function

This gene encodes the homolog of the Drosophila melanogaster Nipped-B gene product and fungal Scc2-type sister chromatid cohesion proteins. The Drosophila protein facilitates enhancer-promoter communication of remote enhancers and plays a role in developmental regulation. It is also homologous to a family of chromosomal adherins with broad roles in sister chromatid cohesion, chromosome condensation, and DNA repair. The human protein has a bipartite nuclear targeting sequence and a putative HEAT repeat domain. Condensins, cohesins and other complexes with chromosome-related functions also contain HEAT repeats.^[1]

Clinical significance

Mutations in this gene result in Cornelia de Lange syndrome, a disorder characterized by dysmorphic facial features, growth delay, limb reduction defects, and mental retardation.^[1]
