Receptor activity modifying protein 2, also known as RAMP2, is a protein

Protein

Proteins are biochemical compounds consisting of one or more polypeptides typically folded into a globular or fibrous form, facilitating a biological function. A polypeptide is a single linear polymer chain of amino acids bonded together by peptide bonds between the carboxyl and amino groups of...

 which in humans is encoded by the RAMP2 gene

Gene

A gene is a molecular unit of heredity of a living organism. It is a name given to some stretches of DNA and RNA that code for a type of protein or for an RNA chain that has a function in the organism. Living beings depend on genes, as they specify all proteins and functional RNA chains...

Function

The protein encoded by this gene is a member of the RAMP

Receptor activity-modifying protein

Receptor activity-modifying proteins are a class of protein which interact with and modulate the activities of several Class B G Protein-Coupled Receptors including the receptors for secretin, calcitonin , glucagon, and vasoactive intestinal peptide...

 family of single-transmembrane-domain proteins, called receptor (calcitonin) activity modifying proteins (RAMPs). RAMPs are type I transmembrane proteins with an extracellular N-terminus and a cytoplasmic C-terminus. RAMPs are required to transport calcitonin-receptor-like receptor

CALCRL

Calcitonin receptor-like , also known as the calcitonin receptor-like receptor , is a human protein.- Function :The protein encoded by the CALCRL gene is a G protein-coupled receptor related to the calcitonin receptor...

 (CRLR) to the plasma membrane. CRLR, a receptor with seven transmembrane domains, can function as either a calcitonin gene-related peptide

Calcitonin gene-related peptide

Calcitonin gene related peptide is a member of the calcitonin family of peptides, which in humans exists in two forms, α-CGRP and β-CGRP. α-CGRP is a 37-amino acid peptide and is formed from the alternative splicing of the calcitonin/CGRP gene located on chromosome 11...
