You can search among core sequence motifs using regular expressions.
Globular domains can often interact with multiple short disordered sequences with regular chemical patterns (consensus motif). The current database contains affinities from the following networks:
Syntax example can be found below:
| Character | Description |
|---|---|
| ^ | Starting position of motif |
| $ | Ending position of motif |
| . | Any single residue |
| [...] | Any residue listed between the square brackets |
| [^...] | Any character not listed between the square brackets |
| p1|p2|p3 | Alternation; matches any of the patterns p1, p2, or p3 |
| {m,n} | m through n instances of preceding element |
Motif examples:
| Motif | Description |
|---|---|
| [ST]P | Motifs that contain either SP or TP sequences |
| SP|TP | The same motifs as above described |
| RRE[ST].L$ | C-terminal motifs with Ser or Thr residues at the antepenultimate position and any residue at the penultimate position |
| T{2,5}V$ | Motifs that end with a Val residue which is preceeded by 2-5 Thr residues |
| .... | All motifs that are at least 4 residue long |
Note 1: Currently, it is not possible to search using explicit PTMs.
Note 2: Motifs are centered based on consensus motifs. Some C-terminal motifs continue with "_".
