Cullin family signature and profile




Description

The following proteins are collectively termed cullins [1]:

  • Caenorhabditis elegans cul-1 (or lin-19), a protein required for developmentally programmed transitions from the G1 phase of the cell cycle to the G0 phase or the apoptotic pathway.
  • Caenorhabditis elegans cul-2, cul-3, cul-4 (F45E12.3), cul-5 (ZK856.1) and cul-6 (K08E7.7).
  • Mammalian CUL1, CUL2, CUL3, CUL4A and CUL4B.
  • Mammalian vasopressin-activated calcium-mobilizing receptor (VACM-1), a kidney-specific protein thought to form a cell surface receptor [2] but which does not have any structural hallmarks of a receptor.
  • Drosophila lin19.
  • Yeast CDC53 [3], which acts in concert with CDC4 and UBC3 (CDC34) to control the G1-to-S phase transition.
  • Yeast hypothetical protein YGR003w.
  • Fission yeast hypothetical protein SpAC24H6.03.

The cullins are hydrophilic proteins of 740 to 815 amino acids. The C-terminal extremity is the most conserved part of these proteins. We have developed a signature pattern from that region.

Note:

This documentation entry is linked to both a signature pattern and a profile. As the profile is much more sensitive than the pattern, you should use it if you have access to the necessary software tools to do so.

Last update:

April 2006 / Pattern revised.
