It also has a N-terminal ring structure and belongs to calcitonin peptide family. ADM has vasodilatory function and is mapped to human chromosome 11p15.4. Adrenomedullin is highly expressed in endothelial cells. Adrenomedullin controls a majority of cellular processes using cyclic adenosine monophosphate (cAMP) as a messenger. It interacts with calcitonin receptor-like receptor (CRLR) and receptor activity modifying protein 2 (RAMP2). ADM contributes to invasion activity in brain tumor cell lines. ADM signalling plays a key role in tumor progression, especially in acute myeloid leukemia._x000D_ Application_x000D_ Adrenomedullin 52 human has been used in tube formation assay in human umbilical vein endothelial cells (HUVECs)._x000D_ Biochem/physiol Actions_x000D_ Peptide elicits potent hypotensive effect, comparable to calcitonin gene-related peptide. Plays a key role in regulating endometrial angiogenesis.
