    Summary
    Enables GTPase activator activity and clathrin binding activity. Acts upstream of or within positive regulation of erythrocyte differentiation and regulation of clathrin-dependent endocytosis. Located in cytoplasm. Is expressed in embryo. Orthologous to human SMAP1 (small ArfGAP 1). [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.
