Expression of gene coding for a melanosomal matrix protein transcriptionally regulated in the transdifferentiation of chick embryo pigmented epithelial cells.


Chicken 115-kDa melanosomal matrix protein (MMP115) was purified from cultured pigmented epithelial cells (PECs), and mouse antiserum was raised to isolate cDNA clones. lambda gt11 expression library made from poly(A)+ RNA of the homogeneous population of PECs was screened with the antiserum. Nine positive clones were obtained from 5 X 10(5) independent… (More)
