[https://www.uniprot.org/uniprot/LASP1_PIG LASP1_PIG] Plays an important role in the regulation of dynamic actin-based, cytoskeletal activities. Agonist-dependent changes in LASP1 phosphorylation may also serve to regulate actin-associated ion transport activities, not only in the parietal cell but also in certain other F-actin-rich secretory epithelial cell types (By similarity).

== Publication Abstract from PubMed ==

The three-dimensional solution structure of the 1:1 complex between the synthetic peptide ZF-1 and zinc was determined by 1H NMR spectroscopy. The peptide, initially isolated from pig intestines, is identical in sequence to the 30 N-terminal amino acid residues of the human protein Lasp-1 belonging to the LIM domain protein family. The final set of 20 energy-refined NMR conformers has an average rmsd relative to the mean structure of 0.55 A for the backbone atoms of residues 3-30. Calculations without zinc atom constraints unambiguously identified Cys 5, Cys 8, His 26, and Cys 29 as the zinc-coordinating residues. LIM domains consist of two sequential zinc-binding modules and the NMR structure of the ZF-1-zinc complex is the first example of a structure of an isolated module. Comparison with the known structures of the N-terminal zinc-binding modules of both the second LIM domain of chicken CRP and rat CRIP with which ZF-1 shares 50% and 43% sequence identity, respectively, supports the notion that the zinc-binding modules of the LIM domain have a conserved structural motif and identifies local regions of structural diversity. The similarities include conserved zinc-coordinating residues, a rubredoxin knuckle involving Cys 5 and Cys 8, and the coordination of the zinc ion by histidine N delta in contrast to the more usual coordination by N epsilon observed for other zinc-finger domains. The present structure determination of the ZF-1-zinc complex establishes the N-terminal half of a LIM domain as an independent folding unit. The structural similarities of N- and C-terminal zinc-binding modules of the LIM domains, despite limited sequence identity, lead to the proposal of a single zinc-binding motif in LIM domains. The coordinates are available from the Brookhaven protein data bank, entry 1ZFO.
