STAM/EAST/Hbp family of proteins consists of eight members well conserved from yeast to mammals. The basic domain architecture is comprised of an N-terminal Vps27, Hrs and STAM homology domain, a ubiquitin-interacting motif and a central Src homology-3 domain. Vertebrate members also carry an immunoreceptor tyrosine-based activation motif. STAM/EAST/Hbp proteins become tyrosine-phosphorylated by a variety of cytokines and growth factors. STAM 1 and STAM 2A are involved in cytokine-mediated signalling for DNA synthesis and c-myc induction. EAST and STAM 2A/Hbp play a role in receptor-mediated endo- and exocytosis and probably also in the regulation of actin cytoskeleton. Knockout experiments implicate a role for STAM 1 in neural cell survival. A picture is emerging of STAM/EAST/Hbp proteins acting as integrators of thus far mechanistically disparate cellular signalling events.
