RANBP1 (RAN Binding Protein 1) is a Protein Coding gene. Among its related pathways are E2F transcription factor network and HIV Life Cycle. RANBP1 encodes a protein that forms a complex with Ras-related nuclear protein (Ran) and metabolizes guanoside triphosphate (GTP). This complex participates in the regulation of the cell cycle by controlling transport of proteins and nucleic acids into the nucleus. There are multiple pseudogenes for RANBP1 on chromosomes 9, 12, 17, and X. Alternative splicing results in multiple transcript variants.
