TNPO1

This gene encodes the beta subunit of the karyopherin receptor complex which interacts with nuclear localization signals to target nuclear proteins to the nucleus. The karyopherin receptor complex is a heterodimer of an alpha subunit which recognizes the nuclear localization signal and a beta subunit which docks the complex at nucleoporins. Alternate splicing of this gene results in several transcript variants encoding different proteins.

Interaction

Identified in a complex that contains TNPO1, RAN and RANBP1 (PubMed:9428644). Binds HNRPA1, HNRPA2, HNRNPDL, RPL23A, RPS7, RPL5, RAN and SRP19. Interacts with H2A, H2B, H3 and H4 histones (By similarity). Interacts with isoform 1 and isoform 5 of ADAR/ADAR1 (via DRBM 3 domain) (PubMed:19124606, PubMed:24753571). Interacts with SNAI1 (via zinc fingers); the interaction mediates SNAI1 nuclear import (PubMed:19386897). Interacts with SNAI2 (via zinc fingers) (PubMed:19386897). (Microbial infection) Binds to HIV-1 Rev.
