About LEFTY1

Cytogenetic location: 1q42.12 Genomic coordinates (GRCh38): 1:225,886,282-225,889,146 (from NCBI)

This gene has 2 transcripts (splice variants), 284 orthologues and 31 paralogues. Biased expression in colon (RPKM 67.2), pancreas (RPKM 11.8) and 2 other tissues.

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. This gene is closely linked to both a related family member and a related pseudogene. [provided by RefSeq, Aug 2016]
