Protein farnesyltransferase/geranylgeranyltransferase type-1 subunit alpha; Essential subunit of both the farnesyltransferase and the geranylgeranyltransferase complex. Contributes to the transfer of a farnesyl or geranylgeranyl moiety from farnesyl or geranylgeranyl diphosphate to a cysteine at the fourth position from the C-terminus of several proteins having the C-terminal sequence Cys-aliphatic- aliphatic-X. May positively regulate neuromuscular junction development downstream of MUSK via its function in RAC1 prenylation and activation.

CAAX prenyl protease 2; Proteolytically removes the C-terminal three residues of farnesylated and geranylated proteins. Seems to be able to process K- Ras, N-Ras, H-Ras, RAP1B and G-gamma-1 (By similarity).

Outer dense fiber protein 3-like protein 2; Belongs to the ODF3 family.

Ketosamine-3-kinase; Ketosamine-3-kinase involved in protein deglycation by mediating phosphorylation of ribuloselysine and psicoselysine on glycated proteins, to generate ribuloselysine-3 phosphate and psicoselysine-3 phosphate, respectively. Ribuloselysine-3 phosphate and psicoselysine-3 phosphate adducts are unstable and decompose under physiological conditions. Not able to phosphorylate fructoselysine ; Belongs to the fructosamine kinase family.

Decaprenyl-diphosphate synthase subunit 1; Supplies decaprenyl diphosphate, the precursor for the side chain of the isoprenoid quinones ubiquinone-10. Belongs to the FPP/GGPP synthase family.

E3 ubiquitin-protein ligase MARCHF6; E3 ubiquitin-protein ligase that promotes 'Lys-48'-linked ubiquitination of target proteins, leading to their proteasomal degradation. Promotes ubiquitination of DIO2, leading to its degradation. Promotes ubiquitination of SQLE, leading to its degradation. E3 ubiquitin ligases accept ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and then directly transfer the ubiquitin to targeted substrates. May cooperate with UBE2G1; Belongs to the DOA10/MARCHF6 family.

CAAX prenyl protease 1 homolog; Proteolytically removes the C-terminal three residues of farnesylated proteins. Acts on lamin A/C.

Distal membrane-arm assembly complex protein 2; Required for the assembly of the mitochondrial NADH:ubiquinone oxidoreductase complex (complex I). Involved in the assembly of the distal region of complex I.

Protein-S-isoprenylcysteine O-methyltransferase; Catalyzes the post-translational methylation of isoprenylated C-terminal cysteine residues; Belongs to the class VI-like SAM-binding methyltransferase superfamily. Isoprenylcysteine carboxyl methyltransferase family.
