The properdin structural locus (Pfc) lies close to the locus for tissue inhibitor of metallothionine proteases (Timp) on the mouse X chromosome.
We have confirmed the assignment of the structural locus of the complement factor properdin (Pfc) to the mouse X chromosome and mapped it between monoamine oxidase-A (Mao-a) and hypoxanthine phosphoribosyltransferase (Hprt) using a Mus spretus x Mus musculus interspecific backcross of 108 animals. The structural locus for murine tissue inhibitor of metallothionine proteases (Timp) could not be separated from properdin in a panel of 18 recombinant animals. By minimizing the number of double recombinants the following gene order was obtained: Otc-Mao-a-(Pfc, Timp)-Hprt-Cf-9. The implications for comparative mapping of human and mouse X chromosomes are discussed.
