Predicted to enable transmembrane signaling receptor activity. Involved in several processes, including T cell activation; hematopoietic stem cell differentiation; and negative regulation of canonical Wnt signaling pathway. Located in endoplasmic reticulum membrane. Is expressed in several structures, including central nervous system; eye; genitourinary system; gut; and immune system. Orthologous to human LMBR1L (limb development membrane protein 1 like). [provided by Alliance of Genome Resources, Apr 2022]
