Gene: Ptger4 (prostaglandin E receptor 4) Rattus norvegicus
Symbol: Ptger4
Name: prostaglandin E receptor 4
RGD ID: 628641
Description: Enables prostaglandin E receptor activity. Involved in several processes, including MAPK cascade; regulation of macromolecule biosynthetic process; and regulation of secretion. Located in neuron projection terminus; neuronal cell body; and nuclear membrane. Used to study acute kidney failure; cystitis; end stage renal disease; myocarditis; and osteoporosis. Biomarker of retinal ischemia and transient cerebral ischemia. Human ortholog(s) of this gene implicated in ankylosing spondylitis; arteriosclerosis; and ulcerative colitis. Orthologous to human PTGER4 (prostaglandin E receptor 4); INTERACTS WITH 17beta-estradiol; 2,3,7,8-tetrachlorodibenzodioxine; 2,3-bis(4-hydroxyphenyl)propionitrile.
