CHUK, a conserved helix-loop-helix ubiquitous kinase, maps to human chromosome 10 and mouse chromosome 19

Helix-loop-helix proteins contain stretches of DNA that encode two amphipathic alpha-helices joined by a loop structure and are involved in protein dimerization and transcriptional regulation essential to a variety of cellular processes. CHUK, a newly described conserved helix-loop-helix ubiquitous kinase, was mapped by somatic cell hybrid analyses to human Chr 10q24-q25. Chuk and a related sequence, Chuk-rs1, were mapped to mouse chromosomes 19 and 16, respectively, by a combination of somatic cell hybrid, recombinant inbred, and backcross analyses.
