[Encoded by MADHIP Gene, ubiquitous cytoplasmic SARA contains a FYVE domain zinc finger, seen in signaling molecules and required for SARA localization but not SMAD interaction. Able to bind PI-3 phosphate, SARA recruits SMAD2/3 to TGFBR. The SMAD binding domain (SBD) of SARA interacts with the SMAD2/3 MH2 domain; the C-terminal domain interacts with TGFBR. SMAD2/SMAD3 phosphorylation induces SARA dissociation, SMAD2/SMAD4 formation, and SMAD nuclear translocation. Alternate isoforms represent full-length (1425-aa, 156-kD) or truncated protein (1210-aa and 762-aa). Disruption of MADHIP appears to be involved in Alzheimer's disease.
