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 × 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.
