CD24 encodes a sialoglycoprotein that is expressed on mature granulocytes and B cells and modulates growth and differentiation signals to these cells. The precursor protein is cleaved to a short 32 amino acid mature peptide which is anchored via a glycosyl phosphatidylinositol (GPI)to the cell surface. CD24 was missing from previous genome assemblies, but is properly located chromosome 6. Non-transcribed pseudogenes have been designated on chromosomes 1, 15, 20, Y. Alternative splicing results in multiple transcript variants. CD24 (CD24 Molecule) is a Protein Coding gene. Among its related pathways are Hematopoietic cell lineage and B Cell Development Pathways.
