Heh2/Man1 may be an evolutionarily conserved sensor of NPC assembly state.
Title: Heh2/Man1 may be an evolutionarily conserved sensor of NPC assembly state.
Flexible and Extended Linker Domains Support Efficient Targeting of Heh2 to the Inner Nuclear Membrane.
Title: Flexible and Extended Linker Domains Support Efficient Targeting of Heh2 to the Inner Nuclear Membrane.
The conserved features of the NLSs of ScHeh1, ScHeh2, and RnPom121 and the effective sorting of Heh2-derived reporters in human cells suggest that active import is conserved but confined to a small subset of INM proteins.
Title: Conservation of inner nuclear membrane targeting sequences in mammalian Pom121 and yeast Heh2 membrane proteins.
Heh2 and Src1/Heh1 contain bipartite import sequences that associate intimately with the minor nuclear localization sequence-binding pocket of yeast importin alpha.
Title: Distinctive Properties of the Nuclear Localization Signals of Inner Nuclear Membrane Proteins Heh1 and Heh2.
study found that at least a 120-residue-long intrinsically disordered linker was required for the import of membrane proteins carrying a nuclear localization signal for the transport factor karyopherin-alpha
Title: Long unfolded linkers facilitate membrane protein import through the nuclear pore complex.
In the absence of the Kap60-44, Kap60-30 and Kap60-10 isoforms, Heh2 localized to cytoplasmic membranes, whereas its wild-type localization at the nuclear periphery was restored when the Kap60-44 isoform was reintroduced.
Title: Truncated isoforms of Kap60 facilitate trafficking of Heh2 to the nuclear envelope.

Preferred Names: Heh2p

NP_010746.1

Inner nuclear membrane (INM) protein; contains helix-extension-helix (HEH) motif, nuclear localization signal sequence; targeting to the INM requires the Srp1p-Kap95p karyopherins and the Ran cycle; HEH2 has a paralog, SRC1, that arose from the whole genome duplication
