- * HMG1/2 signature *
- ********************
-
- High mobility group (HMG) proteins are a family of relatively low molecular
- weight non-histone components in chromatin. HMG1 (also called HMG-T in fish)
- and HMG2 [1] are two highly related proteins that bind single-stranded DNA
- preferentially and unwind double-stranded DNA. HMG1/2 are proteins of about
- 200 amino acid residues with a highly acidic C-terminal section which is
- composed of an uninterrupted stretch of from 20 to 30 aspartic and glutamic
- acid residues; the rest of the protein sequence is very basic.
-
- As a signature pattern we selected a conserved stretch of 12 residues located
- in the N-terminal section of HMG1/2.
-
- -Consensus pattern: [FI]-S-[KR]-K-C-S-[EK]-R-W-K-T-M
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.
