RASSF5 NORE1 RAPL

RASF5

This gene is a member of the Ras association domain family. It functions as a tumor suppressor, and is inactivated in a variety of cancers. The encoded protein localizes to centrosomes and microtubules, and associates with the GTP-activated forms of Ras, Rap1, and several other Ras-like small GTPases. The protein regulates lymphocyte adhesion and suppresses cell growth in response to activated Rap1 or Ras. Multiple transcript variants encoding different isoforms have been found for this gene.

Caution:Has been termed RASSF3 by Ref.3.,Function:Potential tumor suppressor. Seems to be involved in lymphocyte adhesion by linking RAP1A activation upon T cell receptor or chemokine stimulation to integrin activation. Isoform 2 stimulates lymphocyte polarization and the patch-like distribution of ITGAL/LFA-1, resulting in an enhanced adhesion to ICAM1. Together with RAP1A may participate in regulation of microtubule growth. The association of isoform 2 with activated RAP1A is required for directional movement of endothelial cells during wound healing. May be involved in regulation of Ras apoptotic function. The RASSF5-STK4 complex may mediate HRAS1 and KRAS induced apoptosis.,similarity:Contains 1 phorbol-ester/DAG-type zinc finger.,similarity:Contains 1 Ras-associating domain.,similarity:Contains 1 SARAH domain.,subcellular location:Isoform 2 is mainly located in the perinuclear region of unstimulated primary T cells. Upon stimulation translocates to the leading edge and colocalizes with ITGAL/LFA-1 in the peripheral zone of the immunological synapse. Isoform 2 is localized to growing microtubules in vascular endothelial cells and is dissociated from microtubules by activated RAP1A.,subunit:Interacts directly with activated HRAS1; a RASSF5-STK4 complex probably associates with activated HRAS1. Interacts with KRAS. Probably interacts with Ras-like GTPases RRAS, RRAS2, MRAS, RAP1B, RAP2A and RALA. Can self-associate. Interacts with RSSF1 isoform A. The RSSF1 isoform A-RSSF5 heterodimer probably mediates the association of RSSF1 with HRAS1 (By similarity). Isoform 2 interacts with activated RAP1A and ITGAL/LFA-1. Binds STK4/MST1, inhibiting STK4 autoactivation.,tissue specificity:Widely expressed. Frequently down-regulated in lung tumor cell lines and primary lung tumors.,
