BAIT

MCA1

YCA1, Ca(2+)-dependent cysteine protease MCA1, YOR197W
Ca2+-dependent cysteine protease; may cleave specific substrates during the stress response; regulates apoptosis upon H2O2 treatment; required for clearance of insoluble protein aggregates during normal growth; implicated in cell cycle dynamics and lifespan extension; undergoes autocatalytic processing; similar to mammalian metacaspases, but exists as a monomer due to an extra pair of anti-parallel beta-strands that block potential dimerization

Affinity Capture-MS

An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and the associated interaction partner is identified by mass spectrometric methods.

The metacaspase Yca1 maintains proteostasis through multiple interactions with the ubiquitin system.

Shrestha A, Brunette S, Stanford WL, Megeney LA

Metacaspase enzymes are critical regulatory factors that paradoxically engage apoptosis and also maintain cell viability. For example, the Saccharomyces cerevisiae metacaspase Yca1 has been shown to be important for maintaining cellular proteostasis during stress, and the loss of this enzyme results in increased retention of aggregated material within the insoluble proteome. However, the molecular mechanism(s) by which Yca1 maintains cellular ... [more]
