Comments

FUNCTION: Stimulates growth of the cells in an autocrine manner. Mediates hormonal action on the growth of cancer cells.
SUBCELLULAR LOCATION: Secreted.

ALTERNATIVE PRODUCTS: 4 named isoforms [FASTA] produced by alternative splicing. Additional isoforms seem to exist.

Name	FGF-8E
Isoform ID	P55075-1
This is the isoform sequence displayed in this entry.

Name	FGF-8A
Isoform ID	P55075-2
Features which should be applied to build the isoform sequence: VSP_001525.

Name	FGF-8B
Isoform ID	P55075-3
Features which should be applied to build the isoform sequence: VSP_001524.

Name	FGF-8F
Isoform ID	P55075-4
Features which should be applied to build the isoform sequence: VSP_001526.

DEVELOPMENTAL STAGE: In adults expression is restricted to the gonads.
SIMILARITY: Belongs to the heparin-binding growth factors family.
