title: Purification and characterization of three MEKA-like proteins in liver: association of a 94 kDa protein with beta gamma subunits of G-proteins.
abstract: Retinal 32 kDa MEKA protein (rMEKA) exists in the photoreceptor cells and forms a complex with beta gamma subunit of transducin. Bovine liver contained three MEKA-like proteins (94 kDa, 35 kDa-a, 35 kDa-b) which reacted with a rMEKA antibody. Each protein was purified as a single band on a SDS-PAGE and used for a reconstitution experiment with alpha and beta gamma subunits of cerebral G-proteins (Go/i). The 94 kDa protein inhibited GTP-binding ability of G alpha by forming a complex with beta gamma subunit.
