Summary
Predicted to enable amyloid-beta binding activity. Acts upstream of or within plasma cell differentiation. Predicted to be located in membrane. Predicted to be integral component of membrane. Predicted to be active in Golgi apparatus and plasma membrane. Is expressed in several structures, including 1st branchial arch mandibular component; alimentary system; blood; eye; and vault of skull. Orthologous to human ITM2A (integral membrane protein 2A).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
