CAB3

phosphopantothenoylcysteine decarboxylase complex subunit CAB3, YKL088W
Subunit of PPCDC and CoA-SPC complexes involved in CoA biosynthesis; subunits of the phosphopantothenoylcysteine decarboxylase (PPCDC) complex are: Cab3p, Sis2p, Vhs3p, while the subunits of the CoA-synthesizing protein complex (CoA-SPC) are: Cab2p, Cab3p, Cab4p, and Cab5p as well as Sis2p and Vhs3p; null mutant lethality is complemented by E. coli coaBC

SIS2

HAL3, phosphopantothenoylcysteine decarboxylase complex subunit SIS2, L000001899, YKR072C
Negative regulatory subunit of protein phosphatase 1 (Ppz1p); involved in coenzyme A biosynthesis; subunit of phosphopantothenoylcysteine decarboxylase (PPCDC: Cab3p, Sis2p, Vhs3p) complex and the CoA-Synthesizing Protein Complex (CoA-SPC: Cab2p, Cab3p, Cab4p, Cab5p, Sis2p and Vhs3p); SIS2 has a paralog, VHS3, that arose from the whole genome duplication

Reconstituted Complex

An interaction is inferred between proteins in vitro. This can include proteins in recombinant form or proteins isolated directly from cells with recombinant or purified bait. For example, GST pull-down assays where a GST-tagged protein is first isolated and then used to fish interactors from cell lysates are considered reconstituted complexes (e.g. PUBMED: 14657240, Fig. 4A or PUBMED: 14761940, Fig. 5). This can also include gel-shifts, surface plasmon resonance, isothermal titration calorimetry (ITC) and bio-layer interferometry (BLI) experiments. The bait-hit directionality may not be clear for 2 interacting proteins. In these cases the directionality is up to the discretion of the curator.

Molecular characterization of the heteromeric coenzyme A synthesizing protein complex (CoA-SPC) in the yeast Saccharomyces cerevisiae.

Olzhausen J, Moritz T, Neetz T, Schueller HJ

Coenzyme A (CoA) as an essential cofactor for acyl and acetyl transfer reactions is synthesized in five enzymatic steps from pantothenate, cysteine and ATP. In the yeast S. cerevisiae, products of five essential genes CAB1-CAB5 (coenzyme A biosynthesis) are required to catalyze CoA biosynthesis. In addition, non-essential genes SIS2 and VHS3 similar to CAB3 are also involved. Using epitope-tagged variants ... [more]

PCA
PCA

A Protein-Fragment Complementation Assay (PCA) is a protein-protein interaction assay in which a bait protein is expressed as fusion to one of the either N- or C- terminal peptide fragments of a reporter protein and prey protein is expressed as fusion to the complementary N- or C- terminal fragment of the same reporter protein. Interaction of bait and prey proteins bring together complementary fragments, which can then fold into an active reporter, e.g. the split-ubiquitin assay.
