This hormone is not produced in female fetuses, thereby permitting the further differentiation of paramesonephric duct into the uterus and the oviducts. Smaller than littermates. May be a mutation in S100 neurotrophic glial protein. No recombinant with D10Mit139. Not an allele of hes.
Homozygotes show typical circling, head tossing, deafness, and hyperactivity.
Inner ear hair cells degenerate. Female mutants are poor mothers. Expression is induced during the differentiation of B lymphocytes. Has a Kruppel like zinc finger. Induced by Il2 and Il5.
