Domaini

The N-terminal part contains two structurally independent, non-interacting domains: LEM-like (also called LAP2-N or LEM-D) and LEM (also called LAP2-C or LEM-B). LEM-like binds DNA while LEM interacts with BANF1 By similarity.1 Publication
The C-terminal domain forms a four-stranded coiled coil.1 Publication

Sequence similaritiesi

Belongs to the LEM family.
Contains 1 LEM domain.
Contains 1 LEM-like domain.
