NCBI Summary: This gene, a Kirsten ras oncogene homolog from the mammalian ras gene family, encodes a protein that is a member of the small GTPase superfamily. A single amino acid substitution is responsible for an activating mutation. The transforming protein that results is implicated in various malignancies, including lung adenocarcinoma, mucinous adenoma, ductal carcinoma of the pancreas and colorectal carcinoma. Alternative splicing leads to variants encoding two isoforms that differ in the C-terminal region. [provided by RefSeq, Jul 2008]

Seromics Data

Antibody reactivity data from protein arrays and peptide libraries.

HuProt 635 (IgG)

Human proteome microarrays detect autoantibodies against 21,000 full-length proteins via fluorescent immunoassay (HuProt). Median foreground intensity (MFI) from duplicate spots are averaged and log2-transformed. Hits are called when Z-score ≥3 across the array and signal is >4-fold above secondary-only control MFI for that protein. Displayed are Z-scores for patients passing this threshold; non-hits shown as zero. All data are binarized into hit / no-hit for statistics for case vs cohort and case vs control analysis via Fisher exact test with BH correction. Complete data with antigen sequences available for download below. Learn more about our assay platforms.

HuScan Peptide Library

Human phage display immunoprecipitation-sequencing (PhIP-Seq) detects autoantibodies via a >700,000 49mer peptide library covering the human proteome (HuScan). Raw phage counts enriched in each sample are compared to mock-immunoprecipitation controls (beadsonly) via edgeR. Hits are called when P ≤0.0001 and >4-fold above edgeR-computed background. Displayed are log2 fold-changes for patients passing this threshold for peptides matching this gene; non-hits shown as zero. All data are binarized into hit / no-hit for statistics for case vs cohort and case vs control analysis via Fisher exact test with BH correction.
