GK experimental and source evidence

The annotation-specific decisions use the source limits below. Native cache availability and separately inspected originals are recorded independently.

Human enzyme and correction

The purified human enzyme was assayed through PK/LDH coupling. PEP is a coupling reagent; L13943.1 identifies the isoform 1 template.

Source: PMID:37021775. Original Methods and Results; DOI 10.1042/BSR20222258.

Corrected kinetic figures

The linked correction replaces Figures 8–10 after duplicated graphs entered during revision. The editorial assessment retained the underlying data and conclusions. No superseded numerical kinetics are used.

Source: PMID:37860917. Complete correction text; DOI 10.1042/BSR-2022-2258_COR.

Named splice forms

Construct and imaging access limits remain; the named forms do not represent every product.

Source: PMID:15845384. Abstract and selected publisher passages; DOI 10.1016/j.bbrc.2005.03.143.

Patient enzyme evidence

Patient measurements establish enzyme deficiency and glycerol excess; apparent triglyceride elevation does not establish altered triglyceride flux.

Source: PMID:8651297. Original pages 1205–1211, especially Table 1 and Results/Discussion; PMC1915081.

NR4A1 contact

Table S2 row 798 records the validated pair. Figure S5 describes GK-dependent NR4A1 DNA-binding and reporter effects. These supply contact-specific functional context beyond partner classification.

Source: PMID:21988832. Original Methods/Results, Table S2 row 798, Figure S5 caption; PMID21988832.

BioPlex association

Row 67764 names GK P32189-1 and GK2 Q14410. Product grouping and AP-MS association do not establish a functional heteromer.

Source: PMID:33961781. BioPlex3 original table row 67764 and original Methods; PMID33961781.

MuSIC2 association

Network edge 602294 connects GK bait node 602290 to GK2 prey node 602292 in the U2OS AP-MS network.

Source: PMID:40205054. Published NDEx AP-MS network and original Methods; PMID40205054.

Mitochondrial target group

Table S1(A), row 412, group 4491 contains GK and has MitoCoP membership. Adjacent mixed GK/GK3P groups cannot establish a unique product. Membrane topology was not independently resolved by this target row.

Source: PMID:34800366. Actual Table S1 and selected original fractionation/grouping methods; PMID34800366.

Urinary vesicle context

The author-hosted GK/NP_976325 entry has one peptide and reference 2, linking it to this urinary-vesicle study. The literal urine restriction is retained; no modern product crosswalk or target spectrum was independently verified.

Source: PMID:19056867. Author-hosted table row 463 and original preparation/identification methods; PMID19056867.

Catalyst chain

Event 75887 reaches human GK member 55717 through catalyst 76115 and set 3769055. The cytosolic representation is not evidence that every splice product is cytosolic.

Source: Reactome:R-HSA-75887. Official reaction/catalyst/member objects; R-HSA-75887.

Pathway role

The pathway explicitly includes the GK reaction as a precursor-forming step. This is separate from patient pseudohypertriglyceridemia evidence.

Source: Reactome:R-HSA-75109. Official pathway event list; R-HSA-75109.

Product identity and ancestry

Official mappings are P32189-3(GK+EX18) and P32189-4(GK-EX18). Four product sequences are archived.

The inspected PTHR10196 tree places the exact human sequence below the activity IBD at AN0 and the four process/location IBDs at AN364. Literal donor sets, including self-donors, are retained. A cytosol IRD on the target path limits inherited canonical-product localization; independent product-aware human evidence is assessed separately.
