The gene information section lists the gene name (HUGO Gene Nomenclature Committee (HGNC) name if available), any approved gene synonyms, Ensembl gene description, and the Entrez gene summary from the National Center for Biotechnology Information.
The chromosomal and cytoband location of the gene according to Ensembl is reported together with the Ensembl gene identifier and Ensembl database version. The Entrez gene identifier for the gene is also given. If any of the protein products of the gene is linked to a UniProt KB/SWISS-PROT entry, links to the UniProt and the neXtProt databases for these proteins are displayed.

Entrez gene summary
The PNMA1 gene encodes an antineuronal antibody (anti-Ma) present in patients with paraneoplastic neurologic disorders (Dalmau et al., 1999 [PubMed 10050892]). Some paraneoplastic syndromes affecting the nervous system are associated with antibodies that react with neuronal proteins and the causal tumor (onconeuronal antigens) (summarized by Dalmau et al., 1999 [PubMed 10050892]). Several of these antibodies are markers of specific neurologic syndromes associated with distinct types of cancer. The presence of some antibodies is so specific that disorders previously identified by brain biopsy or at autopsy can be diagnosed serologically. The expression of neuronal proteins by the tumor appears to be a crucial step that breaks the immune tolerance for otherwise normal neuronal proteins. The identity of most onconeuronal antigens was established by probing human cDNA expression libraries with serum containing antineuronal antibodies.[supplied by OMIM, May 2010]
The protein view displays protein features. The tabs at the top of the protein view section can be used to switch between the different splice variants encoded by this gene. The mouse over function displays additional data for the features in the protein view.
At the top of the protein view, the maximum percent sequence identity of the protein to all other proteins from other human genes is shown, using a sliding window of 10 aa residues (HsID 10) or 50 aa residues (HsID 50) (read more).
If a signal peptide is predicted by a majority of the signal peptide predictors SPOCTOPUS, SignalP 4.0 and Phobius (turquoise) and/or transmembrane regions (orange) are predicted by MDM, these are displayed.
Common (purple) and unique (grey) regions between alternative processed transcripts from the same gene are also displayed (read more), and at the bottom of the protein view is the protein scale.
The protein information section displays the alternative protein-coding transcripts (splice variants) encoded by this gene, according to the Ensembl database.
The ENSP identifier links to the Ensembl website for that protein, and the ENST identifier links to the Ensembl website for that transcript. The data in the UniProt column can be expanded to show links to all matching UniProt identifiers for this protein.
The protein classes to which this protein has been assigned are shown if expanding the data in the protein class column. Parent protein classes are in bold font and subclasses are listed under the parent class.
The Gene Ontology terms assigned to this protein are listed if expanding the Gene ontology column.
The length of the protein (amino acid residues) (according to Ensembl), molecular mass (kDalton), predicted signal peptide (according to a majority of the signal peptide predictors SPOCTOPUS, SignalP 4.0 and Phobius and predicted transmembrane region(s) (according to MDM) are also reported.
