General annotation (Comments)

Function

This is a receptor for calcitonin. The activity of this receptor is mediated by G proteins which activate adenylyl cyclase. The calcitonin receptor is thought to couple to the heterotrimeric guanosine triphosphate-binding protein that is sensitive to cholera toxin.

Subunit structure

Interacts with GPRASP2. Ref.12

Subcellular location

Cell membrane; Multi-pass membrane protein.

Polymorphism

Genetic variations in CALCR may be correlated with bone mineral density (BMD). Low BMD is a risk factor for osteoporotic fracture. Osteoporosis is characterized by reduced bone mineral density, disrutption of bone microarchitecture, and the alteration of the amount and variety of non-collagenous proteins in bone. Osteoporotic bones are more at risk of fracture.

Sequence similarities

Belongs to the G-protein coupled receptor 2 family.

Alternative products

This entry describes 3 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: P30988-1)

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
Isoform 2 (identifier: P30988-2)

The sequence of this isoform differs from the canonical sequence as follows:
     175-190: Missing.
Isoform 3 (identifier: P30988-3)

The sequence of this isoform differs from the canonical sequence as follows:
     1-47: Missing.
     175-190: Missing.
