Summary: This gene encodes a member of the SFRP family that contains a cysteine-rich domain homologous to the putative Wnt-binding site of Frizzled proteins. Members of this family act as soluble modulators of Wnt signaling; epigenetic silencing of SFRP genes leads to deregulated activation of the Wnt-pathway which is associated with cancer. This gene may also be involved in determining the polarity of photoreceptor cells in the retina. [provided by RefSeq, Sep 2009]

What's a GeneRIF?

Loss of SFRP1 expression is a significant regulator of transcriptional profiles in AH and acts, in part, to limit estrogen signaling. These results support a broader role for SFRP1 in coordinating estrogen-induced responses and WNT signaling in normal breast epithelial cells.

SFRP1 expression is strongly correlated with TNBC on protein level. Associations with age and tumor grade support the role of SFRP1 as a biomarker for chemotherapy response in TNBC.

Functional experiments demonstrated that miR144 promoted proliferation, inhibited apoptosis and induced the osteoblastic differentiation of bone marrowderived mesenchymal stem cells by targeting Sfrp1. It was also shown that miR144 may help regulate Osteoporosis (OP) by activating the Wnt/betacatenin pathway. These data suggest miR144 as a novel target for preventing and treating OP

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
