Dear Jason
a quick look at the HGNC website (http://www.genenames.org) will tell
you that CDC2L1 is the previous name for CDK11B (the currently approved
gene symbol) and similarly CDC2L2 for CDK11A and furthermore that
Ensembl as well as the UCSC genome browser in the meanwhile map them to
the same place in the reference genome and consider them isoforms of the
same gene:
http://www.genenames.org/data/hgnc_data.php?hgnc_id=1729
http://www.genenames.org/data/hgnc_data.php?hgnc_id=1730
OTOH, Entrez and UniProt consider them as separate genes ("Duplicated
gene. CDK11A and CDK11B encode almost identical protein kinases of 110
kDa that ..."): http://www.uniprot.org/uniprot/Q9UQ88
Biology, and the history of biological discovery, can be messy...
Other people might have more insight, but I bet it is a long story :)
