HEAT-like repeat; The HEAT repeat family is related to armadillo/beta-catenin-like repeats (see pfam00514). These EZ repeats are found in subunits of cyanobacterial phycocyanin lyase and other proteins and probably carry out a scaffolding role.

21-101 8.53e-08

Importin-beta N-terminal domain; Members of the importin-beta (karyopherin-beta) family can bind and transport cargo by themselves, or can form heterodimers with importin-alpha. As part of a heterodimer, importin-beta mediates interactions with the pore complex, while importin-alpha acts as an adaptor protein to bind the nuclear localisation signal (NLS) on the cargo through the classical NLS import of proteins. Importin-beta is a helicoidal molecule constructed from 19 HEAT repeats. Many nuclear pore proteins contain FG sequence repeats that can bind to HEAT repeats within importins.. which is important for importin-beta mediated transport.
