Echinoderm Microtubule Associated Protein Like Protein 2 (EML2)

The nucleotide sequence of a human EMAP-related protein-2 (HuEMAP-2) encodes a protein of 649 amino acids in length. The translated polypeptide sequence and domain structure of sea urchin EMAP and HuEMAP-2 are highly conserved, with greater than 57% identity and 77% similarity at the translated amino acid level.Southern blot analysis is consistent with the presence of a single HuEMAP-2 gene in the human genome. Moreover, HuEMAP-2 is a member of a larger protein family with at least four HuEMAP sequences in the NCBI databases. One of these, HuEMAP-1, is identified as the candidate gene for the Usher syndrome 1 a locus. In addition, these RNA blots indicate that HuEMAP-2 transcripts may be differentially spliced in neuronal tissues.
