Summary: Predicted to enable CD4 receptor binding activity; protein phosphatase binding activity; and sialic acid binding activity. Predicted to be involved in several processes, including negative regulation of immunoglobulin production; negative regulation of signal transduction; and regulation of B cell proliferation. Predicted to be located in cell surface and neuronal cell body membrane. Predicted to be active in early endosome; external side of plasma membrane; and recycling endosome. Predicted to be integral component of plasma membrane. Orthologous to human CD22 (CD22 molecule). [provided by Alliance of Genome Resources, Apr 2022]

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.
