Gene Description

CG8841 is an HID1/Ecm30-family protein associated by phylogenetic and similarity inference with Golgi organization, intracellular protein transport, and secretory-granule maturation. Its likely role is in secretory-pathway membrane organization rather than DNA recombination, despite the historical Dmc1 alias; its molecular activity is unresolved.

Existing Annotations Review

GO Term Evidence Action Reason
GO:0000138 Golgi trans cisterna
IBA
GO_REF:0000033
ACCEPT
Summary: Trans-Golgi localization is consistent with conserved HID1 biology.
Reason: IPR026705 identifies the HID1/Ecm30 family and the IBA locates the protein in the Golgi secretory pathway. No target-specific architectural conflict is apparent.
Supporting Evidence:

DR InterPro; IPR026705; HID1/Ecm30.
GO:0003674 molecular_function
ND
GO_REF:0000015
ACCEPT
Summary: Molecular activity remains unresolved.
Reason: HID1-family secretory-pathway participation does not establish an intrinsic enzyme activity or a specific binding reaction.
Supporting Evidence:

DR InterPro; IPR026705; HID1/Ecm30.
GO:0005794 Golgi apparatus
ISS
GO_REF:0000024
ACCEPT
Summary: Golgi localization is a coherent curated family inference.
Reason: The HID1/Ecm30 domain supports the existing ISS Golgi annotation; this is an inferred location rather than a direct fly imaging result.
Supporting Evidence:
file:DROME/CG8841/CG8841-uniprot.txt
DR InterPro; IPR026705; HID1/Ecm30.
GO:0005797 Golgi medial cisterna
IBA
GO_REF:0000033
ACCEPT
Summary: Medial-Golgi residence is retained as a curated phylogenetic inference.
Reason: The specific IBA is compatible with HID1-family Golgi organization and no target-specific evidence of localization loss is established.
Supporting Evidence:
file:DROME/CG8841/CG8841-uniprot.txt
DR InterPro; IPR026705; HID1/Ecm30.
GO:0005829 cytosol
IBA
GO_REF:0000033
ACCEPT
Summary: A cytosolic pool is compatible with peripheral Golgi machinery.
Reason: HID1-family membership supports a protein cycling or associating with cytosolic faces of secretory membranes; the curated IBA is retained as an inference rather than direct localization.
Supporting Evidence:
file:DROME/CG8841/CG8841-uniprot.txt
DR InterPro; IPR026705; HID1/Ecm30.
GO:0006886 intracellular protein transport
ISS
GO_REF:0000024
ACCEPT
Summary: Intracellular protein transport is consistent with HID1-family biology.
Reason: The existing ISS fits the protein's Golgi/secretory-pathway architecture and inferred organization role.
Supporting Evidence:
file:DROME/CG8841/CG8841-uniprot.txt
DR InterPro; IPR026705; HID1/Ecm30.
GO:0007030 Golgi organization
IBA
GO_REF:0000033
ACCEPT
Summary: Golgi organization is a reasonable core family-level process.
Reason: The HID1/Ecm30-family assignment is coherent with the curated IBA Golgi-organization assertion and does not require catalytic activity.
Supporting Evidence:
file:DROME/CG8841/CG8841-uniprot.txt
DR InterPro; IPR026705; HID1/Ecm30.
GO:0016020 membrane
IBA
GO_REF:0000033
ACCEPT
Summary: Membrane association is compatible with a peripheral Golgi factor.
Reason: A retained transmembrane helix is not required for peripheral membrane association; HID1-family biology and the existing IBA support the broad membrane term.
Supporting Evidence:
file:DROME/CG8841/CG8841-uniprot.txt
DR InterPro; IPR026705; HID1/Ecm30.
GO:0061792 secretory granule maturation
IBA
GO_REF:0000033
ACCEPT
Summary: Secretory-granule maturation is retained as a curated family inference.
Reason: HID1-family placement is consistent with a role in Golgi-dependent maturation of secretory cargo. The evidence establishes participation by phylogenetic inference rather than an intrinsic catalytic mechanism.
Supporting Evidence:
file:DROME/CG8841/CG8841-uniprot.txt
DR InterPro; IPR026705; HID1/Ecm30.
