- * Dynamin family signature *
- ****************************
-
- Dynamin [1,2] is a microtubule-associated force-producing protein of 100 Kd
- which is involved in the production of microtubule bundles and which is able
- to bind and hydrolyze GTP. Dynamin is structurally related to the following
- proteins:
-
- - Drosophila shibire protein (gene shi) [3]. Shibire is, very probably, the
- Drosophila cognate of mammalian dynamin. It seems to provide the motor for
- vesicular transport during endocytosis.
- - Yeast vacuolar sorting protein VPS1 (or SPO15) [4], a protein which could
- also be involved in microtubule-associated motility.
- - Yeast protein MGM1 [5], which is required for mitochondrial genome
- maintenance.
- - Interferon induced Mx proteins [6,7]. Interferon alpha or beta induce the
- synthesis of a family of closely related proteins. Most of these proteins
- are known to confer resistance to influenza viruses and/or rhabdoviruses on
- transfected mammalian cell in culture.
-
- The three motifs found in all GTP-binding proteins are located in the N-
- terminal part of these proteins. The signature pattern that we developed for
- these proteins is based on a highly conserved region downstream of the
- ATP/GTP-binding motif 'A' (P-loop).
-
- -Consensus pattern: L-P-[RK]-G-[STN]-[GN]-[LIVM]-V-T-R
- -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.
