14-3-3 and Regulation of BAD Activity

This image is a scaled-down version of the actual pathway image. It does not contain any links to the protein information pages.
 

Description

14-3-3 is a phosphoserine/phosphothreonine-binding protein that is being implicated in a wide range of cellular phenomena. 14-3-3 family members are found in all eukaryotes – from plants to mammals – and more than 100 binding partners have been identified to date. They regulate their activities by a number of different mechanisms, which include inter- and intracompartmental sequestration, activation/inactivation of enzymatic activity and promotion/inhibition of protein interactions. The targets of 14-3-3 are found in all sub cellular compartments and their functional diversity is overwhelming – they include transcription factors, biosynthetic enzymes, cytoskeletal proteins, signaling molecules, apoptosis factors and tumor suppressors (Ref.1 & 2). 14-3-3 family of proteins consists of seven members (ζ, σ, β, η, θ, γ and ε) (Ref.3).
