Functioni

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. SFRP4 may act as a regulator of adult uterine morphology and function. Increases apoptosis during ovulation possibly through modulation of FZ1/FZ4/WNT4 signaling. Has phosphaturic effects by specifically inhibiting sodium-dependent phosphate uptake (By similarity).By similarity

Expressioni

Tissue specificityi

Expressed in the involuting mammary gland, ovarian corpus luteum and prostate. In ovaries, low levels found in granulosa cells. High levels in corpora lutea of pregnant animals.1 Publication

Developmental stagei

Expressed from day 9 of pregnant uterus. Highest level at day 12, specifically in the decidua and weakly, in the myometrium. Levels decline thereafter.1 Publication

Inductioni

Up-regulated 48 hours after estrogen treatment mainly in the uterine endometrial stroma. Induced in ovarian granulosa cells after 12 hours treatment with chorionic gonadotrophin (CG). Further up-regulated in corpora lutea by the luteotrophic hormone PRL.1 Publication

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
