- * Stathmin family signature *
- *****************************
-
- Stathmin [1] (from the Greek 'stathmos' which means relay), is an ubiquitous
- intracellular protein, present in a variety of phosphorylated forms and which
- serves as a relay for diverse second messenger pathways. Its expression and
- phosphorylation are regulated throughout development and in response to
- extracellular signals regulating cell proliferation, differentiation and
- function.
-
- Stathmin is a highly conserved protein of 149 amino acid residues.
- Structurally, it consists of an N-terminal domain of about 45 residues
- followed by a 78 residue alpha-helical domain consisting of a heptad repeat
- coiled coil structure and a C-terminal domain of 25 residues.
-
- Rat protein SCG10 is a neuron-specific, membrane-associated protein that
- accumulates in the growth cones of developing neurons. It is highly similar in
- its sequence to stathmin, but differs in that it contains an additional N-
- terminal hydrophobic segment of 32 residues which is probably responsible for
- its interaction with membranes.
-
- As a signature for stathmin and SCG10, we selected a perfectly conserved
- decapeptide which ends with the first three residues of the coiled coil
- domain.
-
- -Consensus pattern: P-K-K-K-D-L-S-L-E-E
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.
