Isolation of a new member of DnaJ-like heat shock protein 40 (Hsp40) from human liver

摘要

A new member of Hsp40, HLJ1, consisting of 337 amino acids, was cloned from a human liver cDNA library. The deduced amino acid sequence of HLJ1 has an 84% homology (69% identity) with that of HDJ-1 isolated from human placenta. Northern analysis showed that expression of the HLJ1 gene is heat-inducible and its transcription shows some degree of preference in heart, skeletal muscle, and pancreas.
