MGI Phenotype

FUNCTION: 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. Mice lacking a functional copy of this gene exhibit embryonic lethality and defects in left-right patterning. [provided by RefSeq, Aug 2016]
PHENOTYPE: Mice homozygous for a null allele show embryonic and postnatal lethality, abnormal liver lobation, and a variety of left-right positional defects in visceral organs including left thoracic and atrial isomerism. A subset of mice homozygous for a differentnull allele show left pulmonary isomerism. [provided by MGI curators]
