ID:TGFA_HUMAN DESCRIPTION: RecName: Full=Protransforming growth factor alpha; Contains: RecName: Full=Transforming growth factor alpha; Short=TGF-alpha; AltName: Full=EGF-like TGF; Short=ETGF; AltName: Full=TGF type 1; Flags: Precursor; FUNCTION: TGF alpha is a mitogenic polypeptide that is able to bind to the EGF receptor/EGFR and to act synergistically with TGF beta to promote anchorage-independent cell proliferation in soft agar. SUBUNIT: Interacts with the PDZ domains of MAGI3, SDCBP and SNTA1. The interaction with SDCBP, is required for the targeting to the cell surface. In the endoplasmic reticulum, in its immature form (i.e. with a prosegment and lacking full N-glycosylation), interacts with CNIH. In the Golgi apparatus, may form a complex with CNIH and GORASP2. Interacts (via cytoplasmic C-terminal domain) with NKD2. SUBCELLULAR LOCATION: Transforming growth factor alpha: Secreted, extracellular space. SUBCELLULAR LOCATION: Protransforming growth factor alpha: Cell membrane; Single-pass type I membrane protein. TISSUE SPECIFICITY: Isoform 1, isoform 3 and isoform 4 are expressed in keratinocytes and tumor-derived cell lines. SIMILARITY: Contains 1 EGF-like domain.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
