Chromosomal assignments of genes for trypsin, chymotrypsin B, and elastase in mouse

Somat Cell Mol Genet. 1984 Jul;10(4):377-83. doi: 10.1007/BF01535633.


The mouse genes for the serine proteases trypsin (Try-1), chymotrypsin B (Ctrb), and elastase (Ela-1) were chromosomally assigned using Southern blot hybridization of mouse X Chinese hamster cell hybrid DNA. cDNA probes for the three genes were hybridized to cell hybrid DNA cleaved with BamHI or HindIII and the segregation of Try-1, Ctrb, and Ela-1 was correlated with the segregation of mouse chromosomes. Try-1 is located on chromosome 6, Ctrb is on chromosome 8, and Ela-1 is on chromosome 15. The three genes fall into three syntenic groups that are conserved in the mouse and human genomes.
