Description
| Product Name: | Human TGFA Recombinant Protein |
| Product Code: | RPPB0967 |
| Size: | 100µg |
| Species: | Human |
| Target: | TGFA |
| Synonyms: | Transforming Growth Factor Alpha, Protransforming Growth Factor Alpha, TGF-Alpha, TGFA. |
| Source: | Escherichia Coli |
| Physical Appearance: | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Formulation: | Lyophilized from a 0.2�m filtered solution in 0.1% TFA. |
| Solubility: | It is recommended to reconstitute the lyophilized TGFA in sterile 18M-cm H2O not less than 100�g/ml, which can then be further diluted to other aqueous solutions. |

Transforming Growth Factor-Alpha (TGF-alpha) belongs to the EGF family of cytokines. TGFA soluble form is discharged from the membrane by proteolytic cleavage. Membrane-bound proTGF-alpha is biologically active and has a role in cell-cell adhesion or in the stimulation of adjacent cells. TGFA expression is common in transformed cells. Additionally, TGFA is expressed in normal tissues during embryogenesis and in adult cells/tissues, including the pituitary, keratinocytes, and macrophages.
TGFA Human Recombinant (40-89) produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 50 amino acids and having a molecular mass of 5.6kDa. The TGFA is purified by proprietary chromatographic techniques.
| UniProt Protein Function: | TGFalpha: 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. 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. Isoform 1, isoform 3 and isoform 4 are expressed in keratinocytes and tumor-derived cell lines. 5 isoforms of the human protein are produced by alternative splicing. |

| NCBI Summary: | This gene encodes a growth factor that is a ligand for the epidermal growth factor receptor, which activates a signaling pathway for cell proliferation, differentiation and development. This protein may act as either a transmembrane-bound ligand or a soluble ligand. This gene has been associated with many types of cancers, and it may also be involved in some cases of cleft lip/palate. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2011] |
