Journal ArticleDOI
Genistein, a specific inhibitor of tyrosine-specific protein kinases.
Tetsu Akiyama,J Ishida,Shinsaku Nakagawa,Hiroshi Ogawara,Shinya Watanabe,N Itoh,M Shibuya,Yasuo Fukami +7 more
TL;DR: Genistein inhibited the EGF-stimulated increase in phosphotyrosine level in A431 cells and scarcely inhibited the enzyme activities of serine- and threonine-specific protein kinases such as cAMP-dependent protein kinase, phosphorylase kinases, and the Ca2+/phospholipid-dependent enzymeprotein kinase C.
Journal ArticleDOI
Purified protein kinase C phosphorylates microtubule-associated protein 2.
Tetsu Akiyama,Eisuke Nishida,J Ishida,N Saji,Hiroshi Ogawara,Motonori Hoshi,Yoshihiko Miyata,Hiroshi Sakai +7 more
TL;DR: The peptide mapping analysis indicated thatprotein kinase C and cAMP-dependent protein kinase phosphorylate MAP2 differently, raising the possibility that phosphorylation of MAP2 by activated protein kinases C may be involved in cell-surface signal transduction.
