Ras-related protein Rap-2c (RAP2C)

Target
RAP2C
Molecular classification
Small GTPase, Ras oncogene family, Ras superfamily of small GTPases, Enzyme (GTP-binding protein)
01

Overview

Ras-related protein Rap-2c (RAP2C) is a member of the Ras oncogene family of small GTPases, which act as molecular switches in signal transduction pathways. RAP2C, along with RAP2A and RAP2B, regulates a variety of cellular processes including cytoskeletal organization, cell adhesion, migration, and invasion, critical for both physiological and pathological conditions. Recent evidence shows that RAP2C promotes migration and invasion of cancer cells, acting via upregulation of MMP2 activity and stimulation of the PI3K/Akt signaling pathway, but does not impact cell proliferation or apoptosis. Its role in facilitating cancer cell motility and metastatic potential makes RAP2C a candidate therapeutic target, though no approved drugs selectively target it yet.

Mechanism of action

Drugs or inhibitors targeting RAP2C would likely modulate its GTPase activity, thereby affecting cell migration/invasion signaling pathways such as increased MMP2 production and PI3K/Akt-mediated cell motility

03

Biological functions

Signal transductionRegulation of cell migrationRegulation of cell invasionCytoskeletal organizationCell adhesionRegulation of matrix metalloproteinase activityRegulation of Akt phosphorylation
04

Disease associations

Cancer (tumor progression, metastatic potential, especially in osteosarcoma)Other (potential role in cell motility and invasiveness in various cancers)
05

Safety considerations

No specific safety concerns have been documented for RAP2C-targeting agents, but as the pathway is central to cell migration and invasion, unintended effects on normal cell motility and tissue repair could be anticipated
06

Interacting drugs

No clinically approved drugs directly targeting RAP2C have been documented; experimental targeting has been proposed but is not yet established
07

Biomarkers

MMP2 (matrix metalloproteinase-2, levels increased with RAP2C activity)TIMP2 (tissue inhibitor of metalloproteinases 2, levels decrease with RAP2C activity)Phosphorylated Akt (p-Akt)
