title: cDNA cloning, gene characterization and 13q14.3 chromosomal assignment of CHC1-L, a chromosome condensation regulator-like guanine nucleotide exchange factor.
abstract: We report the characterization of a new gene mapped at chromosome band 13q14.3 telomeric to the retinoblastoma gene. This gene, designated CHC1L (for chromosome condensation 1-like), is composed of 14 exons spanning 30 kb of genomic DNA and encodes a ubiquitously expressed 3-kb mRNA. The N-terminal half of the deduced amino acid sequence shows strong homology with the seven tandem repeat structure of the regulator of chromosome condensation RCC1, which acts as a guanine nucleotide exchange factor (GEF) protein for the Ras-related GTPase Ran. CHC1L appears to be a new member of the RCC1-related GEF family.
