Microtubule Associated Protein 1S (MAP1S)

Using the SEC1 homology domain of LRPPRC as probe in a yeast 2-hybrid screen, Liu and McKeehan (2002) cloned VCY2IP1 (BPY2IP1), which they called C19ORF5, from a liver cDNA library.

The deduced 672-amino acid protein is proline-rich (12.8%) and contains an arginine-rich potential RNA-binding motif. VCY2IP1 shares significant homology with several microtubule-associated proteins. Northern blot analysis revealed a major transcript of about 3 kb in all 12 tissues tested. Additional less-abundant transcripts were detected in some tissues.The International Radiation Hybrid Mapping Consortium mapped the VCY2IP1 gene to chromosome 19.
