We have cloned a mouse homologue (designated Myak) of the yeast protein kin
ase YAK1. The 1210 aa open reading frame contains a putative protein kinase
domain, nuclear localization sequences and PEST sequences. Myak appears to
be a member of a growing family of YAK1-related genes that include Drosoph
ila and human Minibrain as well as a recently identified rat gene ANPK that
encode a steroid hormone receptor interacting protein. RNA blot analysis r
evealed that Myak is expressed at low levels ubiquitously but at high level
s in reproductive tissues, including testis, epididymis, ovary, uterus, and
mammary gland, as well as in brain and kidney. In situ hybridization analy
sis on selected tissues revealed that Myak is particularly abundant in the
hormonally modulated epithelia of the epididymis, mammary gland, and uterus
, in round spermatids in the testis, and in the corpora lutea in the ovary,
Myak is also highly expressed in the aqueduct of the adult brain and in th
e brain and spinal cord of day 12.5 embryos, Mol. Reprod. Dev. 55:372-378,
