RPA2 (NM_002946) - replication protein A2

Replication Protein A 32 Kda Subunit Isoform 1

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.

RPA2: replication protein A 32 kDa subunit isoform 1
Description:

This gene encodes a subunit of the heterotrimeric Replication Protein A (RPA) complex, which binds to single-stranded DNA (ssDNA), forming a nucleoprotein complex that plays an important role in DNA metabolism, being involved in DNA replication, repair, recombination, telomere maintenance, and co-ordinating the cellular response to DNA damage through activation of the ataxia telangiectasia and Rad3-related protein (ATR) kinase. The RPA complex protects single-stranded DNA from nucleases, prevents formation of secondary structures that would interfere with repair, and co-ordinates the recruitment and departure of different genome maintenance factors. The heterotrimeric complex has two different modes of ssDNA binding, a low-affinity and high-affinity mode, determined by which oligonucleotide/oligosaccharide-binding (OB) domains of the complex are utilized, and differing in the length of DNA bound. This subunit contains a single OB domain that participates in high-affinity DNA binding and also contains a winged helix domain at its carboxy terminus, which interacts with many genome maintenance protein. Post-translational modifications of the RPA complex also plays a role in co-ordinating different damage response pathways. [provided by RefSeq, Sep 2017].
