Summary: Predicted to enable enzyme binding activity; protein phosphatase activator activity; and ubiquitin-like ligase-substrate adaptor activity. Involved in positive regulation of autophagy; positive regulation of regulatory T cell differentiation; and regulation of transcription by RNA polymerase II. Acts upstream of or within several processes, including autophagy; negative regulation of neuron apoptotic process; and neural tube development. Located in axoneme; cytosol; and phagocytic vesicle. Is active in cytoplasm and nucleus. Is expressed in main olfactory bulb. Orthologous to human AMBRA1 (autophagy and beclin 1 regulator 1). [provided by Alliance of Genome Resources, Jul 2025]

GIT1 interacted with Beclin1 and promoted Beclin1 phosphorylation at Thr119, which induced the disruption of Beclin1 and Bcl2 binding under starvation conditions, thereby, positively regulating autophagy. Taken together, the findings suggest a previously unappreciated role of GIT1 in autophagy of OCs during fracture repair

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.
