General annotation (Comments)

Function

Receptor for bradykinin. It is associated with G proteins that activate a phosphatidylinositol-calcium second messenger system.

Subunit structure

Forms a complex with PECAM1 and GNAQ. Interacts with PECAM1 By similarity.

Subcellular location

Cell membrane; Multi-pass membrane protein.

Tissue specificity

Uterus, vas deferens, kidney, ileum, heart, testis, lung and brain.

Post-translational modification

Diphosphorylation at Ser-365 and Ser-371, at Ser-378 and Ser-380, and at Thr-374 and Ser-380 seem to be correlated pairwise.

Palmitoylation at Cys-356 and phosphorylation at Tyr-352 seem to be mutually exclusive.

Sequence similarities

Belongs to the G-protein coupled receptor 1 family. Bradykinin receptor subfamily. BDKRB2 sub-subfamily.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]
Isoform Long (identifier: P25023-1)

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 Short (identifier: P25023-2)

The sequence of this isoform differs from the canonical sequence as follows:
     1-30: Missing.
