CALCRL
Function
G protein-coupled receptor which specificity is determined by its interaction with receptor-activity-modifying proteins (RAMPs) (PubMed:32296767, PubMed:33602864, PubMed:8626685). Together with RAMP1, form the receptor complex for calcitonin-gene-related peptides CALCA/CGRP1 and CALCB/CGRP2 (PubMed:33602864). Together with RAMP2 or RAMP3, function as receptor complexes for adrenomedullin (ADM and ADM2) (PubMed:32296767, PubMed:9620797). Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and modulates the activity of downstream effectors. Activates cAMP-dependent pathway (PubMed:32296767, PubMed:8626685).
Involvement in disease
Lymphatic malformation 8
LMPHM8
A form of primary lymphedema, a disease characterized by swelling of body parts due to developmental anomalies and functional defects of the lymphatic system. Adult patients with lymphedema may suffer from recurrent local infections. Impaired lymphatic drainage in the fetus can develop into hydrops fetalis, a severe condition characterized by excessive fluid accumulation in more than two fetal extra-vascular compartments and body cavities, placental enlargement and edema, pericardial or pleural effusion, or ascites. LMPHM8 is an autosomal recessive form characterized by onset in utero and fetal death due to non-immune hydrops fetalis.
None
The disease may be caused by variants affecting the gene represented in this entry.
Sequence Similarities
Belongs to the G-protein coupled receptor 2 family.
Tissue Specificity
Predominantly expressed in the lung and heart.
Cellular localization
- Cell membrane
- Multi-pass membrane protein
