Mutations Visualisation
The Mutations Visualisation needle plot provides a visual summary of the location, frequency and functional significance of all known mutations in your protein of interest. The placement of the pins corresponds to the location along the protein’s sequence, while the mutation impact and PTM associated with it is explained in the figure legend.

- Height (y axis) represents the number of occurrences of the mutation
- Horizontal position (x axis) represents the position along your protein’s amino acid sequence
- Pinhead colour represents the mutation impact (figure legend)
- X axis colouring represents the type of PTM associated with the mutation location (figure legend)

Zooming in/out
Too zoom in/out of a specific amino acid sequence, you can either use the magnifying glass icons below the needle plot, or you can use your mouse scroll wheel while hovering over the needle plot. Furthermore, you can enter a specific amino acid sequence range in the search bar and hit “Go!”

Saving the image
The Mutations Visualisation figure can be saved as an SVG or PDF format by clicking on the “Save image as” button at the top right of the plot.

Tracks
While the x axis of the Mutations Visualization plot indicates the amino acid sequence location, additional positional details are visualized using the tracks found here:

- Sequence track: amino acid sequence of your protein of interest
- Disorder track: (Not sure about this myself)
- Domains track: proteins domains identified in the amino acid sequence
- Mutations track: the specific amino acid substitutions detected at the specific site

If there is a specific region of the amino acid sequence you are interested in, you can zoom onto it using the magnifying glass icons below the Mutations Visualization plot. Alternatively, you can zoom in and out by using your mouse scroll wheel while hovering over the needle plot.

Protein summary
The protein summary provides brief information regarding your protein, namely: its full name, a brief description of its function, and genomic location of the coding gene.

This is preferred isoform of HLA-DRA protein.
HLA-DRA: HLA class II histocompatibility antigen, DR alpha chain precursor
Description:

HLA-DRA is one of the HLA class II alpha chain paralogues. This class II molecule is a heterodimer consisting of an alpha and a beta chain, both anchored in the membrane. It plays a central role in the immune system by presenting peptides derived from extracellular proteins. Class II molecules are expressed in antigen presenting cells (APC: B lymphocytes, dendritic cells, macrophages). The alpha chain is approximately 33-35 kDa and its gene contains 5 exons. Exon 1 encodes the leader peptide, exons 2 and 3 encode the two extracellular domains, and exon 4 encodes the transmembrane domain and the cytoplasmic tail. DRA does not have polymorphisms in the peptide binding part and acts as the sole alpha chain for DRB1, DRB3, DRB4 and DRB5. [provided by RefSeq, Jul 2008].
