Gene Expression and Pathophysiology Comments
ADGRL2 mRNA is dysregulated (up or down) in various cancers [13]. More information on the dysregulation of ADGRL2 in cancer can be found on the NCBI Geoprofiles database (http://www.ncbi.nlm.nih.gov/geoprofiles).
General Comments
ADGRL2 (formerly LPHN2, latrophilin 2) is an orphan receptor that belongs to Family I Adhesion-GPCRs along with ADGRL1 (latrophilin 1), ADGRL3 (latrophilin 3) and ADGRL4 (ELTD1) [2]. Family I Adhesion-GPCRs have orthologs in vertebrate and invertebrate species.
