- * CAP-Gly domain signature *
- ****************************
-
- It has been shown [1] that some cytoskeleton-associated proteins (CAP) share
- the presence of a conserved, glycine-rich, domain of about 42 residues (that
- we call here CAP-Gly). The proteins that are known to contain this domain are
- listed below.
-
- - Restin (also know as cytoplasmic linker protein-170 or CLIP-170), a 160 Kd
- protein which is associated with intermediate filaments and that links
- endocytic vesicles to microtubules. Restin contains two copies of the CAP-
- Gly domain.
- - Rat and Drosophila (gene glued) 150 Kd dynein-associated polypeptide (DAP)
- which is involved in dynein-mediated vesicles transport.
- - Yeast protein BIK1 which seems to be required for the formation or
- stabilization of microtubules during mitosis and for spindle pole body
- fusion during conjugation.
- - Caenorhabditis elegans hypothetical protein M01A8.4.
-
- Structurally these proteins are all made of three distinct parts: a N-terminal
- section that is most probably globular and which contains the CAP-Gly domain,
- a large central region which is predicted to be in an alpha-helical coiled-
- coil conformation, and a short C-terminal globular domain. The only exception
- is the C.elegans protein which only consist of the CAP-Gly domain.
-
- The signature for the CAP-Gly domain corresponds to the first 32 residues of
- the domain and contains six of the seven conserved glycines.
-
- -Consensus pattern: G-x(6)-G-x-[FYW]-x-G-[LIVM]-x-[LIVM]-x(4)-G-K-[NH]-x-G-
- [STA]-x(2)-G-x(2)-Y-F
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.
- -Last update: June 1994 / Pattern and text revised.
