PF01937: Damage-control phosphatase ARMT1-like domain
IPR002791: integrated entry for Damage-control phosphatase ARMT1-like domain
Source description
This domain is widely distributed in all domains of life and occur in stand-alone form and as C-terminal fusions to pantothenate kinase (PanK) in plants and animals. They are metal-dependent phosphatases involved in metabolic damage-control processes termed "damage pre-emption" or "housecleaning". S.cerevisiae Damage-control phosphatase YMR027W and the human orthologue Damage-control phosphatase ARMT1 (also known as C6orf211) are involved in response to DNA damage, a damage pre-emption function. Crystal structure of Damage-control phosphatase At2g17340 from Arabidopsis revealed a novel protein fold and several conserved residues coordinating a metal ion (probably Mg2+), which exhibits a high degree of conservation, suggesting that the metal-binding site is central for the function [InterPro reference PUB00088733].

No scoring reasons supplied.
Related Mech records
This family joined the worklist after the frozen cross-Mech scan, so other Mechs were not searched for it. Missing links here are not evidence that other Mechs lack it; rows shown come from mentions of a former DUF/UPF name.
No cross-Mech examples are present in the supplied snapshot.

Status and evidence
- Seed status
- A name-based classification of frozen InterPro/Pfam metadata. UNKNOWN CANDIDATE means the metadata explicitly says the function is unknown. KNOWN HISTORICAL DUF means a DUF name matched without that wording; this heuristic is not proof of a known function and does not establish experimental characterization. EX DUF means Pfam renamed the family away from a DUF/UPF name, as recorded in Pfam's previous identifiers; a rename usually follows published work on some members but is naming history, not proof of function for every member. Some EX DUF families' current names or descriptions still say the function is unknown; their classification basis lists this, and scoring does not treat them as characterized. FALSE POSITIVE TEXT HIT means the naming rules did not match.
- Characterization
- A separate evidence-scoring result. UNSCORED means no score has been calculated; it is not evidence that the family lacks a known function. Missing scores are not negative evidence. PARTIALLY CHARACTERIZED has partial support; KNOWN HISTORICAL DUF can inherit the seed label or reflect a known-function signal. Neither label implies experimental validation.
- Evidence counts
- Source-specific signals, not unique proteins, publications, or confidence scores. Known counts Rhea reactions and experimentally supported GO molecular-function annotations. Partial counts functional/domain assignments. Context counts structural, environmental, orthology, interaction and neighborhood signals; context alone does not assign function. Repeated annotations may not be independent.
- Curation status
- Reported separately from seed classification and characterization. SNAPSHOT ONLY means no curated metadata was supplied for this build. SEEDED denotes a source-derived record, not an expert-reviewed functional claim.
- Missing counts
- Not available means the source did not supply that counter. A zero is a reported count. Not scored means evidence counts are unavailable.
