171 Attenuation of the ATPase ActiVity by Nucleotide Binding Domain Interaction Is Altered in the Stargardt Mutant R2038W. Login to comment
172 The NBD2 mutation, R2038W, leads to significant reductions in the rate of ATP hydrolysis as well as the affinity of ATP binding (67). Login to comment
173 To evaluate how this mutation affected the nucleotidase activity of the NBD1‚NBD2 complex, analysis of the ATPase activity of the R2038W mutant protein alone and in complex with wild-type NBD1 was carried out. Login to comment
199 The affinity of interaction decreased under all conditions examined, as determined by comparison of the Kd values (Table Table 2: Modulation of ATPase Activities of NBD1‚NBD2 Complexes by Site-Specific Mutations NBD1‚NBD2 mutation domain NBD1‚NBD2 ATPasea (pmol/min) NBD1‚NBD2 ATPaseexptl (pmol/min) NBD1‚NBD2 ATPasecalcd b (pmol/min) motif/disease NBD1mut‚NBD2wt K969A, T970A NBD1 1.9 ( 0.4/5.3 ( 0.1 5.1 ( 0.1 7.2 synthetic NBD1wt‚NBD2mut K1978A, 1979A NBD2 3.1 ( 0.2/1.6 ( 0.3 1.5 ( 0.2 4.7 synthetic NBD1mut‚NBD2wt P940R NBD1 1.9 ( 0.3/5.2 ( 0.2 4.3 ( 0.1 7.1 AMD NBD1wt‚NBD2mut R2038W NBD2 3.1 ( 0.1/2.0 ( 0.2 4.4 ( 0.2 5.1 STGD NBD1wt‚NBD2wt wild type N/A 3.0 ( 0.3/5.4 ( 0.1 5.30 ( 0.3 8.4 none a Experimental ATPase activity corresponding to 6 pmol of the individual domains, NBD1 and NBD2, respectively.

111 To compare this observation directly with our previous report (Lewis et al. 1999), we replaced five mutations (A1038V, L2027F, R2030Q, R2038W, V2050L) to linker regions. Login to comment

130 Among these four reported mutations, p.A1773V in ABCA4 was reported as one of the founder mutations (up to17%) in Latin American population [18]; p.R2038W mutation in USA, Estonia and South African population; p.R602W mutation in USA, South African population [2,3,19]; G607R in the German population[20].

131 Taken together, this study confirmed that these four mutations are pathogenic mutations and among these four reported mutations, p.A1773V, p.R2038W and p.R602W may have higher allele frequencies since they were frequently reported in different populations. Login to comment
