ALG1 (YBR110W, P16661) notes

Pathway context: cytoplasmic-face LLO assembly (GlcNAc2-PP-Dol + GDP-Man -> Man1GlcNAc2-PP-Dol, EC 2.4.1.142).

• First (beta-1,4) mannosyltransferase. PMID:6368538 PMID:7037780
• Forms separate complexes with Alg2 and Alg11. PMID:15044395
• ER membrane, N-terminal TM, catalytic domain cytoplasmic. PMID:29939232 PMID:29939232

Curation observations
- Protein binding IPIs (Alg2, Alg11) removed as uninformative; the complexes are real. GO:0031501 mannosyltransferase complex could capture them (not proposed here).
- RCA cytosol -> GO:0098554 (already IDA).
