Journal ArticleDOI
Isolation and sequence of a cDNA clone for human tyrosinase that maps at the mouse c-albino locus.
TL;DR: Southern blot analysis of DNA derived from newborn mice carrying lethal albino deletion mutations revealed that Pmel34 maps near or at the c-albino locus, the position of the structural gene for tyrosinase.
Journal ArticleDOI
The Tyrosine Hydroxylase Activity of Mammalian Tyrosinase
TL;DR: Dopa is the most effective hydrogen donor and will eliminate the lag period when used in catalytic amounts and 3,4-Dihydroxyphenylalanine at high concentration is an inhibitor of tyrosine hydroxylation, while tyrosinase acts as a substrate inhibitor at concentrations above 8 x 10-4 m.
Journal ArticleDOI
Regulation of tyrosinase in human melanocytes grown in culture.
TL;DR: It is concluded that tyrosinase activity in cultures of human melanocytes derived from different donors is determined predominantly by its abundance.
Journal ArticleDOI
Inhibition of Oocyte Maturation by Porcine Follicular Fluid: Partial Characterization of the Inhibitor
TL;DR: The inhibitory action of FF1 upon oocyte maturation was not destroyed by heating to60#{176}Corby repeatedfreezing and thawing and could not be removed byextraction with charcoal, but the inhibitory activity was abolished by trypsin digestion.
