On the other hand, motifs define amino acid arrangements conserved between protein family members and represent powerful tools for assigning function to protein sequences. The ideal motif would identify all members of a protein family but in practice many motifs identify both family members and unrelated proteins, referred to as True Positive (TP) and False Positive (FP) sequences, respectively.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>To address the relationship between protein motifs, protein function and cellular localization, we systematically assigned subcellular localization data to motif sequences from the comprehensive PROSITE sequence motif database. Using this data we analyzed relationships between localization and function. We find that TPs and FPs have a strong tendency to localize in different compartments. When multiple localizations are considered, TPs are usually distributed between related cellular compartments. We also identified cases where FPs are concentrated in particular subcellular regions, indicating possible functional or evolutionary relationships with TP sequences of the same motif.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions<\/jats:title>\n            <jats:p>Our findings suggest that the systematic examination of subcellular localization has the potential to uncover evolutionary and functional relationships between motif-containing sequences. We believe that this type of analysis complements existing motif annotations and could aid in their interpretation. Our results shed light on the evolution of cellular organelles and potentially establish the basis for new subcellular localization and function prediction algorithms.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1186\/1471-2105-14-229","type":"journal-article","created":{"date-parts":[[2013,7,18]],"date-time":"2013-07-18T00:15:07Z","timestamp":1374106507000},"update-policy":"http:\/\/dx.doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Classification of protein motifs based on subcellular localization uncovers evolutionary relationships at both sequence and functional levels"],"prefix":"10.1186","volume":"14","author":[{"given":"Marcos","family":"Parras-Molt\u00f3","sequence":"first","affiliation":[]},{"given":"Francisco J","family":"Campos-Laborie","sequence":"additional","affiliation":[]},{"given":"Juan","family":"Garc\u00eda-Di\u00e9guez","sequence":"additional","affiliation":[]},{"given":"M Rosario","family":"Rodr\u00edguez-Gri\u00f1olo","sequence":"additional","affiliation":[]},{"given":"Antonio J","family":"P\u00e9rez-Pulido","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2013,7,18]]},"reference":[{"key":"5985_CR1","doi-asserted-by":"publisher","first-page":"33812","DOI":"10.1074\/jbc.M112.367839","volume":"287","author":"D Bouayad","year":"2012","unstructured":"Bouayad D, Pederzoli-Ribeil M, Mocek J, Candalh C, Arlet JB, Hermine O, Reuter N, Davezac N, Witko-Sarsat V: Nuclear-to-cytoplasmic relocalization of the proliferating cell nuclear antigen (PCNA) during differentiation involves a chromosome region maintenance 1 (CRM1)-dependent export and is a prerequisite for PCNA antiapoptotic activity in mature neutrophils.
