[Genome] protein ID / align ID

[Anton Kratz]

Hi,



In the UCSC KnownGene (May 2004) dataset, why are there sometimes genes
which differ only in the protein ID and align ID fields?

For example NM_001001486 and NM_001001487 (exact description below) look
identical in structure, only protein ID and align ID are different.
I wonder what makes them different genes? Could you shortly explain the
meaning of protein ID and align ID fields (how to interpret them)?



Regarding different align ID, I thought it means that the KnownGene maps to
different locations on the genome with same quality. But start - end
positions are identical here.



regards,

Anton
