HAP2 (P06774) bioinformatics: PANTHER subfamily placement

Method

panther_subfamily.py (run with uv run --script panther_subfamily.py > panther_subfamily.json)
queries the PANTHER geneinfo web service (PANTHER release 19) for the family and
subfamily of S. cerevisiae HAP2 (P06774), N. crassa NCU03033 (Q7SGY4) and human NFYA
(P23511). The raw output is in panther_subfamily.json.

Results

accession organism PANTHER family PANTHER subfamily
P06774 S. cerevisiae HAP2 PTHR12632 PTHR12632:SF6
Q7SGY4 N. crassa NCU03033 PTHR12632 PTHR12632:SF6
P23511 human NFYA PTHR12632 PTHR12632:SF6

HAP2, NCU03033 and human NFYA are all placed in the same PANTHER subfamily,
PTHR12632:SF6 (NUCLEAR TRANSCRIPTION FACTOR Y SUBUNIT ALPHA). The UniProt and InterPro
PANTHER cross-references for P06774 and Q7SGY4 give only the family PTHR12632 with no
subfamily; the subfamily assignment comes only from the PANTHER service.

Interpretation

Because the three proteins share a subfamily, the core NF-YA/HAP2 properties, CCAAT-box
recognition as part of the HAP2/3/5 (NF-YA/B/C) heterotrimer and subunit assembly
through the conserved core, can be transferred within this subfamily. The
yeast-specific HAP4-dependent activation of respiratory genes depends on HAP4, a
Saccharomycetaceae-type activation subunit. Subfamily membership alone does not
show that this regulon is conserved.
