Disease relevance of CPXM1
- Furthermore, CPX-1 expressed in either the baculovirus system or the mouse AtT-20 cell line does not cleave standard CP substrates [1].
High impact information on CPXM1
- In situ hybridization of CPX-1 mRNA in embryonic and fetal mouse tissue showed expression throughout the head and thorax, with abundance in primordial cartilage and skeletal structures [1].
- Northern blot analysis showed the highest levels of CPX-1 mRNA in testis and spleen and lower levels in salivary gland, brain, heart, lung, and kidney [1].
- In the head, high levels of CPX-1 mRNA were associated with the nasal mesenchyme, primordial cartilage structures in the ear, and the meninges [1].
- Instead, CPX-1 may have a role in development, possibly mediating cell interactions via its discoidin domain [1].
- In the thorax, CPX-1 mRNA was expressed in multiple developing skeletal structures, including chondrocytes and perichondrial cells of the rib, vertebral, and long-bone primordia [1].
Biological context of CPXM1
- However, several active-site residues that are important for catalytic activity of other CPs are not conserved in CPX-1 [1].
Other interactions of CPXM1
- Identification of mouse CPX-1, a novel member of the metallocarboxypeptidase gene family with highest similarity to CPX-2 [1].
