# PPP4R4: human–horse sequence comparison

The downloaded human Q6NUP7 sequence (873 residues) and selected horse A0A9L0S961 sequence (865 residues) share 95.0% identity among 865 paired residues. Paired coverage is 99.1% of human and 100.0% of horse.

Full alignment, hashes, parameters and reproducible script: [PPP4R4.json](../../../../projects/PROTNLM_EVALUATION/mammal-benchmark/paired-sequences/PPP4R4.json) and [compare.py](../../../../projects/PROTNLM_EVALUATION/mammal-benchmark/paired-sequences/compare.py).

Pairwise similarity supports homology but does not establish reciprocal orthology, intact gene models, conservation of targeting signals or every biological claim. Current UniProt sequences are compared; identity with the original ProtNLM input sequence is unverified.
