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. {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. Interacts (via cytoplasmic C-terminal
CC       domain) with NKD2 (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Transforming growth factor alpha: Secreted,
CC       extracellular space {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Protransforming growth factor alpha: Cell
CC       membrane {ECO:0000250}; Single-pass type I membrane protein
CC       {ECO:0000250}.
