About LEFTY2

Cytogenetic location: 1q42.12 Genomic coordinates (GRCh38): 1:225,936,603-225,941,220 (from NCBI)

This gene has 3 transcripts (splice variants), 284 orthologues, 31 paralogues and is associated with 2 phenotypes. Biased expression in endometrium (RPKM 129.5) and ovary (RPKM 10.7).

Summary

This gene encodes a secreted ligand of the TGF-beta (transforming growth factor-beta) superfamily of proteins. Ligands of this family bind various TGF-beta receptors leading to recruitment and activation of Smad Family transcription factors that regulate gene expression. The encoded preproprotein is proteolytically processed to generate the mature protein, which plays a role in left-right asymmetry determination of organ systems during development. The protein may also play a role in endometrial bleeding. Mutations in this gene have been associated with left-right axis malformations, particularly in the heart and lungs. Some types of infertility have been associated with dysregulated expression of this gene in the endometrium. This gene is closely linked to both a related family member and a related pseudogene. This gene encodes multiple isoforms that may undergo similar proteolytic processing. [provided by RefSeq, Aug 2016]
