Ras-related protein Rap-1A is a protein that in humans is encoded by the RAP1A gene. [5]
The product of this gene belongs to the family of Ras-related proteins. These proteins share approximately 50% amino acid identity with the classical RAS proteins and have numerous structural features in common. The most striking difference between RAP proteins and RAS proteins resides in their 61st amino acid: glutamine in RAS is replaced by threonine in RAP proteins. The product of this gene counteracts the mitogenic function of RAS because it can interact with RAS GAPs and RAF in a competitive manner. Two transcript variants encoding the same protein have been identified for this gene. [6]
RAP1A has been shown to interact with:
RAF proto-oncogene serine/threonine-protein kinase, also known as proto-oncogene c-RAF or simply c-Raf or even Raf-1, is an enzyme that in humans is encoded by the RAF1 gene. The c-Raf protein is part of the ERK1/2 pathway as a MAP kinase (MAP3K) that functions downstream of the Ras subfamily of membrane associated GTPases. C-Raf is a member of the Raf kinase family of serine/threonine-specific protein kinases, from the TKL (Tyrosine-kinase-like) group of kinases.
Ras homolog gene family, member B, also known as RHOB, is a protein which in humans is encoded by the RHOB gene.
Tuberous Sclerosis Complex 2 (TSC2), also known as Tuberin, is a protein that in humans is encoded by the TSC2 gene.
Afadin is a protein that in humans is encoded by the AFDN gene.
Rap1 GTPase-activating protein 1 is an enzyme that in humans is encoded by the RAP1GAP gene.
Ras-related protein Rab-11A is a protein that in humans is encoded by the RAB11A gene.
RHEB also known as Ras homolog enriched in brain (RHEB) is a GTP-binding protein that is ubiquitously expressed in humans and other mammals. The protein is largely involved in the mTOR pathway and the regulation of the cell cycle.
Regulator of chromosome condensation 1, also known as RCC1, Ran guanine nucleotide exchange factor and RanGEF, is the name for a human gene and protein.
Ras-related protein Ral-A (RalA) is a protein that in humans is encoded by the RALA gene on chromosome 7. This protein is one of two paralogs of the Ral protein, the other being RalB, and part of the Ras GTPase family. RalA functions as a molecular switch to activate a number of biological processes, majorly cell division and transport, via signaling pathways. Its biological role thus implicates it in many cancers.
Ral guanine nucleotide dissociation stimulator is a protein that is encoded by the RALGDS gene in humans.
Ras-related protein R-Ras is a protein that in humans is encoded by the RRAS gene.
Ras-related protein Rap-2a is a protein that in humans is encoded by the RAP2A gene. RAP2A is a member of the Ras-related protein family.
Rnd1 is a small signaling G protein, and is a member of the Rnd subgroup of the Rho family of GTPases. It is encoded by the gene RND1.
Ras-related protein Rap-2b is a protein that in humans is encoded by the RAP2B gene. RAP2B belongs to the Ras-related protein family.
Ras-related protein M-Ras, also known as muscle RAS oncogene homolog and R-Ras3, is a protein that in humans is encoded by the MRAS gene on chromosome 3. It is ubiquitously expressed in many tissues and cell types. This protein functions as a signal transducer for a wide variety of signaling pathways, including those promoting neural and bone formation as well as tumor growth. The MRAS gene also contains one of 27 SNPs associated with increased risk of coronary artery disease.
Retinal rod rhodopsin-sensitive cGMP 3',5'-cyclic phosphodiesterase subunit delta is an enzyme that in humans is encoded by the PDE6D gene. PDE6D was originally identified as a fourth subunit of rod cell-specific cGMP phosphodiesterase (PDE). The precise function of PDE delta subunit in the rod specific GMP-PDE complex is unclear. In addition, PDE delta subunit is not confined to photoreceptor cells but is widely distributed in different tissues. PDE delta subunit is thought to be a specific soluble transport factor for certain prenylated proteins and Arl2-GTP a regulator of PDE-mediated transport.
SH2 domain containing 3C, also known as SH2D3C, is a protein that in humans is encoded by the SH2D3C gene.
Rap guanine nucleotide exchange factor 2 is a protein that in humans is encoded by the RAPGEF2 gene.
Ras-related GTP-binding protein A is a protein that in humans is encoded by the RRAGA gene.
Rap guanine nucleotide exchange factor 5 is a protein that in humans is encoded by the RAPGEF5 gene.
