RT   cell secretion: structural requirements for activity.";
RL   Regul. Pept. 43:37-47(1993).
CC   -!- FUNCTION: TGF alpha is a mitogenic polypeptide that is able to
CC       bind to the EGF receptor/EGFR and to act synergistically with TGF
CC       beta to promote anchorage-independent cell proliferation in soft
CC       agar (By similarity). Inhibitor of acid secretion. Inhibitor of
CC       aminopyrine uptake in parietal cells (in vitro). {ECO:0000250}.
CC   -!- SUBUNIT: Interacts with the PDZ domains of MAGI3, SDCBP and SNTA1.
CC       The interaction with SDCBP, is required for the targeting to the
CC       cell surface. In the endoplasmic reticulum, in its immature form
CC       (i.e. with a prosegment and lacking full N-glycosylation),
CC       interacts with CNIH. In the Golgi apparatus, may form a complex
CC       with CNIH and GORASP2 (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted, extracellular space {ECO:0000250}.
CC   -!- TISSUE SPECIFICITY: Gastric parietal cells.
