'''CRYSTAL STRUCTURE OF RECOMBINANT BOVINE NEUROCALCIN DELTA AT 2.4 ANGSTROMS'''
== Function ==
 
[https://www.uniprot.org/uniprot/NCALD_BOVIN NCALD_BOVIN] May be involved in the calcium-dependent regulation of rhodopsin phosphorylation. Binds three calcium ions.

==Overview==
[[Image:Consurf_key_small.gif|200px|right]]
The crystal structure of calcium-bound unmyristoylated bovine neurocalcin from Escherichia coli has been determined at 2.4 A resolution. The three-dimensional structure reveals a highly compact structure consisting of: (i) two pairs of calcium-binding EF-hands (EF1-EF2 and EF3-EF4); (ii) a calcium ion bound at EF2, EF3 and EF4 sites; and (iii) an EF1-hand that is disabled from calcium-binding due to a Cys-Pro sequence in the Ca2+-binding loop. The crystal structure of neurocalcin resembles photoreceptor recoverin in overall topology, however its EF2- and EF4-hands differ. Recently, neurocalcin in the calcium-bound state has been shown to stimulate mammalian rod outer segment membrane guanylate cyclase. A possible site for cyclase activity based on the three-dimensional structure is discussed.
