– Plays an important role in the regulation of cell proliferation and cell differentiation. Required for normal regulation of the hair growth cycle. Functions as an inhibitor of hair elongation by promoting progression from anagen, the growth phase of the hair follicle, into catagen the apoptosis-induced regression phase. FGF-5 Protein, Mouse, Recombinant (His) is expressed in E. coli expression system with N-6xHis tag. The predicted molecular weight is 32.8 kDa and the accession number is P15656.
