- * HBGF/FGF family signature *
- *****************************
-
- Heparin-binding growth factors I and II (HBGF) [1,2] (also known as acidic and
- basic fibroblast growth factors (FGF) are structurally related mitogens which
- stimulate growth or differentiation of a wide variety of cells of mesodermal
- or neuroectodermal origin. These two proteins belong to a family of growth
- factors and oncogenes which is currently known [3,4] to include:
-
- - FGF-3 (int-2), induced by the integration of mouse mammary tumor virus
- (MMTV).
- - FGF-4 (hst-1; KS3), a transforming protein independently isolated from a
- human stomach tumor (hst-1) and from Kaposi's sarcoma (KS3).
- - FGF-5, an oncogene expressed in neonatal brain.
- - FGF-6 (hst-2), a transforming protein that exhibits strong mitogenic and
- angiogenic properties.
- - FGF-7 or keratinocyte growth factor (KGF), a paracrine effector of normal
- epithelial cell proliferation.
- - FGF-9 or glia-activating factor (GAF), a heparin-binding growth factor that
- may have a role in glial cell growth and differentiation during
- development.
-
- From the sequences of these related proteins, we have derived a signature
- pattern which includes one of the two conserved cysteine residues.
-
- -Consensus pattern: G-x-L-x-[STAG]-x(6)-[DE]-C-x-F-x-E
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.
