Corticotropin-releasing factor receptor 1

Gene

CRHR1

Organism
Macaca mulatta (Rhesus macaque)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at transcript leveli

Functioni

G-protein coupled receptor for CRH (corticotropin-releasing factor) and UCN (urocortin). Has high affinity for CRH and UCN. Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and down-stream effectors, such as adenylate cyclase. Promotes the activation of adenylate cyclase, leading to increased intracellular cAMP levels. Inhibits the activity of the calcium channel CACNA1H. Required for normal embryonic development of the adrenal gland and for normal hormonal responses to stress. Plays a role in the response to anxiogenic stimuli.1 Publication

Expressioni

Tissue specificityi

Expressed abundantly in the pituitary, cerebral cortex, hippocampus, amygdala and cerebellum.1 Publication

Interactioni

Subunit structurei

Heterodimer; heterodimerizes with GPER1. Interacts (via N-terminal extracellular domain) with CRH and UCN. Interacts with DLG1; this inhibits endocytosis of CRHR1 after agonist binding (By similarity).By similarity

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.
