Data Filters

Show only the mutations which affect specific PTM sites and/or in specific populations (updates both the Mutations Visualisation plot and table found on the Sequence View tab, and the PTM Interaction Network Visualisation plot found on the Network View tab)

PTM mutations only

Enabling this option will cause the search results to display all mutations (by default, only mutations affecting PTM sites are shown initially)

PTM mutations only

Mutation dataset

This option allows you to select the source of mutation data, which in turn also allows you to select different mutation subsets in the respective submenu (appears once you select the dataset source).

Cancer (TCGA PanCancerAtlas): this exome sequencing dataset allows you to select mutations based on the cancer type in which the mutation was detected. To select specific cancer type(s), de-select “All cancer types”, and then select the cancer type(s) you are interested in – multiple selection can be made.

Clinical (ClinVar): this dataset allows you to select mutations based on their clinical and pathological significance, and disease in which that clinical significance was detected in based on data on the ClinVar database. Selection this option will provide you with two submenus: “Clinical significance” and “Disease name”. To select a specific clinical significance and/or disease, de-select that “All clinical significance” and/or “All disease names” prior to making you selection(s).

Population (ESP6500): this dataset allows you to selected mutations reported in either European American or African American individuals based on exome sequencing of thousands of individuals.

Population (1000 Genomes): Similar to ESP 6500, this genome sequencing dataset allows you to select mutations reported in specific ethnic backgrounds. To select specific ethnic background(s), de-select “All ethnicities” prior to making your selection(s).

Kinases

Circle: kinases interacting with your protein of interest (centre of the figure) via the specific PTM site as indicated in the network diagram. The colour of the kinase is shaded based on the number of mutations occurring in that kinase.

Octagon: kinase families interacting with your protein of interest (centre of the figure) via the specific PTM site as indicated in the network diagram. The colour of the kinase is shaded based on the number of mutations occurring in that kinase.

Loss of interaction predicted

Presence of a connecting line between a mutation and kinase denotes the existence of an interaction at this amino acid location. A dashed red line however denotes that the specific mutation causes a loss of interaction.

PTM Interaction Network Visualisation

The PTM Interaction Network provides visualization of all PTMs which mediate an interaction between your protein of interest and protein kinases. Each PTM is visualized as a different colour box listing the mutation location and the surrounding amino acid sequence. These PTMs originate from your protein of interest (circle with a dark border) which links it to a kinase (circle with thick border). The colour of the circles corresponds to the number of mutations occurring in the kinase with white being none, and dark blue being a normalized maximum. See figure legend for additional details.

Zooming in/out
If there is a specific PTM you are interested in, you can click on it to zoom onto it and the kinases it has been associated with. Alternatively you can click the magnifying glass icons on the top right of the PTM Interaction Network Visualisation window.

Saving the image
The Interaction Network image can be saved in an SVG or PDF formats by clicking on the “Save image as” button on the top right of the PTM Interaction Network Visualization window.

APOA4: apolipoprotein A-IV precursor

Description:

Apoliprotein (apo) A-IV gene contains 3 exons separated by two introns. A sequence polymorphism has been identified in the 3'UTR of the third exon. The primary translation product is a 396-residue preprotein which after proteolytic processing is secreted its primary site of synthesis, the intestine, in association with chylomicron particles. Although its precise function is not known, apo A-IV is a potent activator of lecithin-cholesterol acyltransferase in vitro. [provided by RefSeq, Jul 2008].
