Enables parathyroid hormone receptor activity. Acts upstream of or within several processes, including G protein-coupled receptor signaling pathway; bone resorption; and osteoblast development. Predicted to be located in several cellular components, including apical plasma membrane; basolateral plasma membrane; and brush border membrane. Predicted to be integral component of plasma membrane. Predicted to be part of receptor complex. Predicted to be active in plasma membrane. Is expressed in several structures, including extraembryonic component; integumental system; limb; lung; and skeleton. Human ortholog(s) of this gene implicated in Eiken syndrome; Jansen's metaphyseal chondrodysplasia; chondrodysplasia Blomstrand type; osteochondrodysplasia; and primary failure of tooth eruption. Orthologous to human PTH1R (parathyroid hormone 1 receptor). [provided by Alliance of Genome Resources, Apr 2022]
