This gene encodes a member of the TGF-beta (transforming growth factor-beta) superfamily of proteins. The encoded preproprotein is proteolytically processed to generate a subunit of the dimeric activin and inhibin protein complexes. These complexes activate and inhibit, respectively, follicle stimulating hormone secretion from the pituitary gland. Polymorphisms near this gene are associated with pre-eclampsia in female human patients. [provided by RefSeq, Aug 2016]
Forensic Context
A study in rhesus macaques identified the INHBB as a differentially expressed gene upregulated in left ventricular tissue from animals with hypertrophic cardiomyopathy and sudden cardiac death, indicating its association with this cardiac disease process [Rivas et al. DOI:10.1038/s41598-024-82770-4]. In human ovarian cancer, integrative multi-omics analysis found the INHBB to be part of a TGF-beta signaling pathway module, where its gene expression was coordinately regulated with specific DNA methylation markers and microRNAs, revealing its role in a perturbed oncogenic network [Zhang et al. DOI:10.1093/nar/gks725].
