DnaJ/HSP40 Homolog Subfamily C, Member 9 (DNAJC9)

By sequencing clones obtained from a size-fractionated brain cDNA library, Nagase et al. (1999) cloned DNAJC9, which they designated KIAA0974. The transcript contains repetitive elements in its 3-prime UTR, and the deduced protein contains 565 amino acids. RT-PCR ELISA detected moderate expression in all tissues and specific brain regions examined, with highest levels in kidney, testis, ovary, and fetal liver.

Takamura et al. (2001) cloned rat Dnajc9, which they called Jdd1. In situ hybridization revealed strong Jdd1 expression in the germinal zone of rat central nervous system, and Jdd1 expression continued after birth. Jdd1 expression was also detected in embryonic rat liver, lung, and kidney cortex.
