GPR155: Gene organization, multiple mRNA splice variants and expression in mouse central nervous system

► Mouse GPR155 mRNA comprised five variants including newly identified four variants. ► The most abundantly expressed Variant 1 is probably a 17-TM membrane protein. ► Variant 1 and Variant 5 proteins have a conserved DEP-domain near the C-terminal. ► GPR155 mRNAs are widely expressed in adult mouse tissues and during development. ► The highest level of expression is in the lateral striatum and the hippocampus.
