title: Chromosomal assignment and imprinting tests for the mouse delta subunit of the cytosolic chaperonin containing TCP-1 (Cct4) gene to proximal chromosome 11.
abstract: The CCT (chaperonin containing TCP-1) complex functions as a molecular chaperone in the eukaryotic cytosol. This complex consists of several species of related polypeptides. The chromosomal localization of the mouse Cct4 gene encoding the delta subunit of CCT was assigned in this study to proximal chromosome 11 by genetic mapping. Restriction mapping analysis using YAC and pulse-field gel electrophoresis showed that Cct4 is located within a region about 300 kb from the imprinted gene U2af1-rs1. Expression of Cct4 was biallelic, and therefore Cct4 is not imprinted in neonatal mice. The localization of the human homologue of Cct4 on chromosome 2 corresponds well with the fact that homologues of other genes in the proximal region of mouse chromosome 11 also map to the region of conserved synteny in human chromosome 2.
