PF08939: Basophilic leukemia-expressed protein Bles03
IPR015034: integrated entry for Basophilic leukemia-expressed protein Bles03

Source description

This domain is found in Basophilic leukemia-expressed protein Bles03 from humans (also known as UPF0696 protein C11orf68, Q9H3H3 (UniProtKB protein)) and various proteins from eukaryotes, bacteria and archaea. Bles03 has been suggested to have phosphothreonine lyase activity and to play a role in the biosynthesis of dehydro amino acids [InterPro reference PUB00039014]. It shows a two-layer sandwich architecture with a a nine-stranded beta-sheet and three alpha-helices on each side [InterPro reference PUB00100679].

Pfam membership is not functional evidence. Whole-protein sequences do not establish domain boundaries. A coverage gap here is not absence from UniProt.

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.
