CC -!- FUNCTION: Receptor for R-spondins that potentiates the canonical Wnt
CC signaling pathway and is involved in the formation of various organs.
CC Upon binding to R-spondins (RSPO1, RSPO2, RSPO3 or RSPO4), associates
CC with phosphorylated LRP6 and frizzled receptors that are activated by
CC extracellular Wnt receptors, triggering the canonical Wnt signaling
CC pathway to increase expression of target genes. In contrast to
CC classical G-protein coupled receptors, does not activate heterotrimeric
CC G-proteins to transduce the signal. Its function as activator of the
CC Wnt signaling pathway is required for the development of various
CC organs, including liver, kidney, intestine, bone, reproductive tract
CC and eye. May also act as a receptor for norrin (NDP), such results
CC however require additional confirmation in vivo. Required during
CC spermatogenesis to activate the Wnt signaling pathway in peritubular
CC myoid cells. Required for the maintenance of intestinal stem cells and
CC Paneth cell differentiation in postnatal intestinal crypts. Acts as a
CC regulator of bone formation and remodeling. Involved in kidney
CC development; required for maintaining the ureteric bud in an
CC undifferentiated state. Involved in the development of the anterior
CC segment of the eye. Required during erythropoiesis. Also acts as a
CC negative regulator of innate immunity by inhibiting TLR2/TLR4
CC associated pattern-recognition and pro-inflammatory cytokine
CC production. Plays an important role in regulating the circadian rhythms
CC of plasma lipids, partially through regulating the rhythmic expression
CC of MTTP. Required for proper development of GnRH neurons (gonadotropin-
CC releasing hormone expressing neurons) that control the release of
CC reproductive hormones from the pituitary gland (By similarity).
CC {ECO:0000250|UniProtKB:A2ARI4, ECO:0000250|UniProtKB:Q9BXB1}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:Q9BXB1};
CC Multi-pass membrane protein {ECO:0000250|UniProtKB:Q9BXB1}.
CC -!- SIMILARITY: Belongs to the G-protein coupled receptor 1 family.
CC {ECO:0000255|PROSITE-ProRule:PRU00521}.
