Monomer. Interacts with
RANGAP1, which promotes
RAN-mediated GTP hydrolysis. Interacts with
KPNB1 (PubMed:15864302). Interaction with
KPNB1 inhibits
RANGAP1-mediated stimulation of GTPase activity. Interacts with
RCC1 which promotes the exchange of
RAN-bound GDP by GTP. Interaction with
KPNB1 inhibits
RCC1-mediated exchange of
RAN-bound GDP by GTP. Interacts (GTP-bound form) with
TNPO1; the interaction is direct. Interacts (GTP-bound form) with
TNPO3; the interaction is direct (By similarity). Interacts with
KPNB1 and with
TNPO1; both inhibit
RAN GTPase activity. Interacts (via C-terminus) with
RANBP1, which alleviates the inhibition of
RAN GTPase activity. Interacts with
RANGRF, which promotes the release of bound guanine nucleotide.
RANGRF and
RCC1 compete for an overlapping binding site on
RAN. Identified in a complex with
KPNA2 and
CSE1L; interaction with
RANBP1 mediates dissociation of
RAN from this complex (PubMed:15602554). Interaction with both
RANBP1 and
KPNA2 promotes dissociation of the complex between
RAN and
KPNB1. Identified in a complex composed of
RAN,
RANGAP1 and
RANBP1. Identified in a complex that contains
TNPO1,
RAN and
RANBP1. Identified in a nuclear export complex with
XPO1. Found in a nuclear export complex with
RANBP3 and
XPO1. Interacts with
RANBP2/NUP358. Interaction with
RANBP1 or
RANBP2 induces a conformation change in the complex formed by
XPO1 and
RAN that triggers the release of the nuclear export signal of cargo proteins. Component of a nuclear export receptor complex composed of
KPNB1,
RAN,
SNUPN and
XPO1 (By similarity). Found in a nuclear export complex with
RAN,
XPO5 and pre-miRNA (PubMed:19965479). Interacts (GTP-bound form) with
XPO5 (PubMed:19965479). Part of a complex consisting of
RANBP9,
RAN,
DYRK1B and
COPS5. Interacts with
RANBP9 and
RANBP10. Interacts in its GTP-bound form with
BIRC5/survivin at S and M phases of the cell cycle. Interacts with
TERT; the interaction requires hydrogen peroxide-mediated phosphorylation of
TERT and transports
TERT to the nucleus. Interacts with
MAD2L2. Interacts with
VRK1 and
VRK3. Interacts with
VRK2 (By similarity). Interacts with
NEMP1 and
KPNB1 (By similarity). Interacts (GDP-bound form) with
NUTF2; regulates
RAN nuclear import (PubMed:9533885). Interacts with
CAPG; mediates
CAPG nuclear import. Interacts with
NUP153. Interacts with the AR N-terminal poly-Gln region; the interaction with AR is inversely correlated with the poly-Gln length (By similarity). Interacts with
MYCBP2, which promotes
RAN-mediated GTP hydrolysis (By similarity). Interacts with
EPG5 (By similarity).
