Also known as: Siglec-G; Siglec10; mSiglec-G; 9830164H23; A630096C01Rik
Summary: Predicted to enable SH2 domain binding activity; phosphatase binding activity; and sialic acid binding activity. Involved in several processes, including negative regulation of immunoglobulin production; negative regulation of inflammatory response to wounding; and regulation of B cell proliferation. Acts upstream of or within hematopoietic progenitor cell differentiation. Predicted to be active in plasma membrane. Is expressed in liver and thymus primordium. Orthologous to several human genes including SIGLEC10 (sialic acid binding Ig like lectin 10). [provided by Alliance of Genome Resources, Dec 2024]

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.
