COMPLEX BETWEEN RABBIT MUSCLE ALPHA-ACTIN: HUMAN GELSOLIN DOMAIN 1


Contents

Overview

The structure of the segment 1 domain of gelsolin, a protein that fragments actin filaments in cells, is reported in complex with actin. Segment 1 binds monomer using an apolar patch rimmed by hydrogen bonds in a cleft between actin domains. On the actin filament model it binds tangentially, disrupting only those contacts between adjacent subunits in one helical strand. The segment 1 fold is general for all segments of the gelsolin family because the conserved residues form the core of the structure. It also provides a basis for understanding the origin of an amyloidosis caused by a gelsolin variant.

Disease

Known disease associated with this structure: Amyloidosis, Finnish type OMIM:[137350]
