Hello, It seems that you are looking at the track named "UCSC Genes"? If so, this track contains data from multiple sources: RefSeq, Genbank, CCDS and UniProt. The transcripts from these sources are compared to create a unique set of transcripts that produce distinct protein translations. When there is more than one transcript for a gene, then each transcript represents one of these variants. Clicking on a UCSC Gene's transcript in the Assembly browser will link to a details page with much more information about the sequence, including the source, references, other similar mRna data, and supporting documentation or links to external documentation.
If you are looking at transcripts from distinct tracks, then click on the track's name link from the main Assembly browser to view the data source, contacts, and references. If you have a scientific question about a particular transcript, the source group that created the transcript would be the best contact. The Help and FAQ sections offer tutorials and other information to help navigate the Browser and associated tools. If you have any questions, we are glad to help, Jennifer Jackson UCSC Genome Bioinformatics Group [email protected] wrote: > Hi, I'm Dr Nocchi Linda from Marche Polytechnic University (Ancona, > Italy). > I have seen that in your database "Genomes", there are more sequences > for the same gene (for example, in my interest, NNMT human has 2 > sequences one longer than the other) that aren't in NCBI (entrez gene). > Why?
