SCGB1C2 is the HGNC/Ensembl-approved symbol for secretoglobin family 1C member 2
(ENSG00000268320), consistent with the UniProt P0DMR2 description.
"SCGB1C2 is the HGNC/Ensembl-approved symbol for **“secretoglobin family 1C member 2”**"
-
No SCGB1C2-specific functional biochemistry (substrate/ligand specificity, catalytic
activity, or receptor binding) has been directly reported, so no enzyme reaction,
transporter substrate, or pathway position can be asserted from primary evidence.
"SCGB1C2-specific functional biochemistry (substrate/ligand specificity, catalytic activity, receptor binding) was **not directly reported**; therefore, no enzyme reaction, transporter substrate, or specific pathway position can be asserted from primary evidence in this session."
-
Within 2023-2024 primary literature, no direct SCGB1C2-focused functional studies were
found; the only concrete progress is methodological (why SCGB1C2 is hard to validate).
"direct SCGB1C2-focused functional studies were not found"
-
SCGB1C2 is a neXtProt "missing protein": all of its tryptic peptides (>=9 aa) overlap
with SCGB1C1 variants and it can be completely subsumed by SCGB1C1, so it cannot be
uniquely validated by mass spectrometry and proteomics hits may be mis-assigned.
"all tryptic peptides (≥9 aa) from SCGB1C2 overlap with variants of SCGB1C1...SCGB1C2 can be “completely subsumed by” SCGB1C1, making MS-based validation impractical"
-
Reported airway-disease proteomics dysregulation (e.g. strong down-regulation in CRSwNP
nasal lavage) is for the paralog SCGB1C1, not SCGB1C2, and must not be used as direct
SCGB1C2 evidence.
"A 2024 nasal lavage fluid proteomics study in chronic rhinosinusitis with nasal polyposis (CRSwNP) reports strong down-regulation of **SCGB1C1 (secretoglobin family 1C member 1)**"
