Vertebrates exhibit numerous left-right (L-R) asymmetries, such as the position of the heart and spleen on the left side.
L-R polarity is determined early during development, around the presomite stage in mammals.
Several genes have been shown to be expressed asymmetrically relative to the L-R axis.
Meno et al.
(1996, 1997) identified 2 transforming growth factor-beta-related genes, Lefty1 and Lefty2, that are expressed on the left side of developing mouse embryos.Kosaki et al.
(1999) characterized 2 homologs of the murine Lefty1 and Lefty2 genes, which they designated LEFTY B and LEFTY A, respectively.
Both genes encode proteins with 366aa.
The deduced aa sequences of LEFTY B and LEFTY A are more similar to each other than to mouse Lefty1 or Lefty2.
