Nucleic Acids Res
PMCID: 5888019
PMID: 29420790
DOI: 10.1093/nar/gky086

[…] rposition of Mre11 and Rad50 (ATP-bound) on the tetrameric complex structure from M. jannaschii (PDB ID: 5F3W) (). This structure was then refined by molecular dynamics. A multiple alignment based on AL2CO structural conservation () of ScMre11 with Mre11 orthologs from Homo sapiens (PDB ID:3T1I), Schizosaccharomyces pombe (PDB ID:4FCX), Chaetomium thermophilum (PDB ID:4KYE and 5DA9 for RBD region) […]

LAR RPTP Clustering Is Modulated by Competitive Binding between Synaptic Adhesion Partners and Heparan Sulfate

2017
PMCID: 5645493
PMID: 29081732
DOI: 10.3389/fnmol.2017.00327

[…] 38 on IL1RAPL1 also participate in a broad range of interactions with the PTPδ* Ig3 domain. A sequence conservation analysis was performed on the sequences listed in Supplementary Table S3, using the AL2CO (Pei and Grishin, ; Pettersen et al., ). It showed that the key residues at Interface I and Interface II involved in the lateral interaction are highly conserved (Supplementary Figure S3C). […]

[…] y sequence and with conservation of the cysteine residues. Protein models were rendered in UCSF Chimera version 1.10.2 []. Conservation scores were calculated using the UCSF Chimera implementation of AL2CO under the default settings [,]. Tests for selection were performed using HyPhy version 2.220150316: overall dN/dS value was calculated using the AnalyzeCodonData method, persistent site-by-site […]

When loss of function is loss of function: assessing mutational signatures and impact of loss of function genetic variants

2017
Bioinformatics
PMCID: 5870554
PMID: 28882004
DOI: 10.1093/bioinformatics/btx272

[…] on features for the wildtype sequence were extracted from two sources. First, we generated a position-specific scoring matrix (PSSM) by running PSI-BLAST against the "nr" database (). Second, we used AL2CO () to derive nine conservation indexes from the UCSC Genome Browser 46-species alignment () for each position in the sequence. Both normalized and unnormalized versions of these scores were calc […]

[…] Analysis of positional conservation in a sequence alignment can aid in the detection of functionally and/or structurally important residues. The AL2CO program performs conservation analysis in a comprehensive and systematic way. It was used to calculate the conservation index for each position for a given multiple sequence alignment. Twelve d […]

[…] at have known function, functional feature annotations for each protein position were obtained from UniProt on July 18th 2015. To determine the conservation of each domain position j, we employed the AL2CO [] algorithm for assessing entropy via the following formula: Hjh=−∑i=1,20p(ai,j)ln⁡(p(ai,j)) Here, p(ai,j) is the amino acid frequency for amino acid ai at position j and Hj is the AL2CO score […]
