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 protein is also important in self-renewal and differentiation of mouse embryonic stem cells. Mice lacking a functional copy of this gene exhibit defects in axial and left-right patterning.

LEFTY2 alleviates hepatic stellate cell activation and liver fibrosis by regulating the TGF-beta1/Smad3 pathway.
Title: LEFTY2 alleviates hepatic stellate cell activation and liver fibrosis by regulating the TGF-β1/Smad3 pathway.
Endometrial receptivity is negatively regulated by LEFTY2. LEFTY2 inhibits the expression of key murine receptivity genes. LEFTY2 downregulates the expression of Orai1 and inhibits SOCE. LEFTY2 and the Orai1 blockers 2-APB, MRS-1845, and YM-58483 inhibit COX2, BMP2, and WNT4 expression in endometrial cells. Targeting LEFTY2 and Orai1 may represent a novel approach for treating unexplained infertility.
Title: LEFTY2 inhibits endometrial receptivity by downregulating Orai1 expression and store-operated Ca(2+) entry.
LEFTY2 regulates the expression and activity of ENaC in endometrial epithelial cells via SGK1.
Title: LEFTYA Activates the Epithelial Na+ Channel (ENaC) in Endometrial Cells via Serum and Glucocorticoid Inducible Kinase SGK1.
Results indicate that microRNA miR-127 accelerates mesendoderm differentiation of embryonic stem cells through nodal signaling by targeting left-right determination factor 2 (Lefty2).
Title: MicroRNA-127 Promotes Mesendoderm Differentiation of Mouse Embryonic Stem Cells by Targeting Left-Right Determination Factor 2.
Studies indicate that the pair of Nodal and Lefty (Lefty1 and Lefty2) has a conserved role in left-right asymmetry.
Title: TGFβ signaling in establishing left-right asymmetry.
Taken together, these results suggest that optimal expression of Lefty1 and Lefty2 is critical for the balanced differentiation of mESCs into three germ layers.
Title: Lefty1 and lefty2 control the balance between self-renewal and pluripotent differentiation of mouse embryonic stem cells.
ectopic expression of the Nodal inhibitor Lefty2 in the node of Nodal(neo/+) embryos resulted in a phenotype similar to that of the Nodal(neo/neo) mutant

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
