Putative uncharacterized protein YNL028W; Dubious open reading frame; unlikely to encode a functional protein, based on available experimental and comparative sequence data.

Phosphatidylinositol 4,5-bisphosphate-binding protein SLM2; Phosphoinositide PI4,5P(2) binding protein, forms a complex with Slm1p; acts downstream of Mss4p in a pathway regulating actin cytoskeleton organization in response to stress; TORC2 complex substrate and effector; SLM2 has a paralog, SLM1, that arose from the whole genome duplication.

Ceramide synthase subunit; single-span ER membrane protein associated with Lag1p and Lac1p and required for ceramide synthase activity, null mutant grows extremely slowly and is defective in ceramide synthesis; Belongs to the LIP1 family.

Alpha-1,3-mannosyltransferase; adds the fourth and fifth alpha-1,3-linked mannose residues to O-linked glycans during protein O-glycosylation; Belongs to the MNN1/MNT family.

Alpha-1,3-mannosyltransferase MNT2; Mannosyltransferase; involved in adding the 4th and 5th mannose residues of O-linked glycans; Belongs to the MNN1/MNT family.

Mannosyltransferase KTR6; Probable mannosylphosphate transferase; involved in the synthesis of core oligosaccharides in protein glycosylation pathway; member of the KRE2/MNT1 mannosyltransferase family; KTR6 has a paralog, KRE2, that arose from the whole genome duplication; Belongs to the glycosyltransferase 15 family.

Alpha-1,2-mannosyltransferase; responsible for addition of the first alpha-1,2-linked mannose to form the branches on the mannan backbone of oligosaccharides, localizes to an early Golgi compartment; Belongs to the MNN1/MNT family.

Translation initiation factor eIF5; functions both as a GTPase-activating protein to mediate hydrolysis of ribosome-bound GTP and as a GDP dissociation inhibitor to prevent recycling of eIF2; Belongs to the eIF-2-beta/eIF-5 family.

Dephospho-CoA kinase CAB5; Subunit of the CoA-Synthesizing Protein Complex (CoA-SPC); subunits of this complex are: Cab2p, Cab3p, Cab4p, Cab5p, Sis2p and Vhs3p; probable dephospho-CoA kinase (DPCK) that catalyzes the last step in coenzyme A biosynthesis; null mutant lethality is complemented by human homolog DCAKD and by E. coli coaE (encoding DPCK); detected in purified mitochondria in high-throughput studies; also localized to lipid droplets.
