    Summary
    Enables AP-2 adaptor complex binding activity; clathrin heavy chain binding activity; and insulin receptor binding activity. Involved in clathrin-dependent endocytosis and gastrulation. Acts upstream of or within insulin receptor internalization; negative regulation of glucose import; and negative regulation of signal transduction. Located in clathrin-coated endocytic vesicle; lysosome; and plasma membrane. Is expressed in embryo; extraembryonic component; neural fold; and primitive streak. Human ortholog(s) of this gene implicated in methylmalonic aciduria and homocystinuria type cblF. Orthologous to human LMBRD1 (LMBR1 domain containing 1).

    What's a GeneRIF?
    1. By studying the heterozygous knockout of Lmbrd1 (Lmbrd1(+/-)), we discovered that lack of Lmbrd1 not only resulted in the increase of cardiac-glucose uptake, pathological consequences were also observed. The results suggested that Lmbrd1 gene not only plays a significant role in mediating the energy homeostasis in cardiac tissue, it may also be a key factor in the regulation of cardiac function in mice.

    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.
