  • 功能：
    Soluble frizzled-related proteins (sFRPS) function as modulators of Wnt signaling through direct interaction with Wnts. They have a role in regulating cell growth and differentiation in specific cell types. SFRP5 may be involved in determining the polarity of photoreceptor, and perhaps, other cells in the retina.

    7. The inverse association of serum Sfrp5 with beta-cell function suggests a detrimental role of Sfrp5 for insulin secretion also in humans. The severity of NAFLD does not appear to affect this relationship. The weak association between serum Sfrp5 and insulin sensitivity was partially explained by body mass. PMID: 27019073
    8. Results identify several coding and non-coding variants in the sFRP5 gene region, the majority of which resulted in a non-synonymous amino acid change in the protein. One of the variants (c.-3G[A) shows a trend towards association between the variant frequency and the obese phenotype. PMID: 27497818
