| − | === Why built the HMM? ===
| + | |
| − | We built the profile because the boundary of phosphatase domain defined by Pfam profile is not the same as the one reported in crystal structure study <cite>Begley03</cite> and SMART does not have the profile for the myotubularin phosphatase domain. The crystal structure shows the phosphatase domain ranges from 205-586 in human MTMR2 (Figure 6A in <cite>Begley03</cite>). The Pfam profile [http://pfam.xfam.org/family/PF06602.10 Myotub-related (PF06602)] predicted the range from 192-529, which lacks the C-terminal ~45 aa.

| − | We PSI-BLASTed the region from 190 to 600 of human MTMR2. The region is the phosphatase domain determined in crystal structure study with flanking regions <cite>Begley03</cite>:

| − | We first PSI-BLASTed the region against RefSeq database via NCBI BLAST server. We found 5000+ hits in 1st round, which is difficult to look into. We then PSI-BLASTed the region against RefSeq database via NCBI BLAST server. The coverage of human myotubularins:
| + | |
| − | * MTM1, MTMR1, MTMR2: ~190-600, 100%
| + | |
| − | * MTMR3: ~214-595 (human, rat, mouse); MTMR4: ~225-588 (human, mouse), ~213-598 (xenopus)

| − | Note: In addition to PSI-BLAST, we tried to obtain an alignment from HHPRED, but the quality is pretty bad.

| − | === How was the HMM built? ===
| + | |
| − | We PSI-BLASTed the region against PSI-BLASTed, which converged right after 1st round.
