High impact information on FUS2

  • We found that polarisome components and the cell fusion proteins Fus1 and Fus2 are important for the termination of projection growth [1].
  • Based on double mutant analysis, AXL1 in a MATalpha strain acted genetically in the same pathway with FUS2, a fusion-dedicated gene [2].
  • Rvs161p interacts with Fus2p to promote cell fusion in Saccharomyces cerevisiae [3].
  • FUS2 encodes a unique open reading frame of 617 residues that only is expressed in haploid cells in response to mating pheromone [4].
  • These, and other results suggest that Fus2 defines a novel cell fusion function and subcellular structure that is also required for the alignment of parental nuclei before nuclear fusion [4].

Biological context of FUS2


Anatomical context of FUS2

  • Consistent with a role in cell fusion, Fus2 protein localizes with discrete structures that could be of cytoskeletal or vesicular origin that accumulate at the tip of pheromone-induced shmoos and at the junction of paired cells in zygotes [4].
  • Fus2 is predicted to be a coiled-coil protein and fractionates with a 100,000 g pellet, suggesting that it is associated with cytoskeleton, membranes, or other macromolecular structures [4].

Other interactions of FUS2

  • In contrast, Fus2p and Rvs161p appeared to act after vesicle positioning [7].
  • In addition, we found that the defect in default mating caused by mutations in SPA2 is partially suppressed by multiple copies of two genes, FUS2 and MFA2 [8].
  • We characterized two genes, FUS1 and FUS2, which are required for fusion of Saccharomyces cerevisiae cells during conjugation [9].
