WPP domain interacting protein 3;(source:Araport11)
TAIR Curator Summary
Encodes an outer nuclear membrane protein that anchors RanGAP1 to the nuclear envelope. It interacts with SUN proteins and is required for maintaining the elongated nuclear shape of epidermal cells.
First observed in roots and cotyledons of young developing seedlings. Later confined to root tips and cauline leaves tips. In flowers, detected in the stamens and at the senescence region of developing siliques.
Mediates and enhances the nuclear envelope docking of RANGAP proteins mediated by WIT1 and WIT2 in the undifferentiated cells of root tips (PubMed:17600715). As component of the SUN-WIP-WIT2-KAKU1 complex, mediates the transfer of cytoplasmic forces to the nuclear envelope (NE), leading to nuclear shape changes (PubMed:25759303).
