Background: Vasodilator-stimulated phosphoprotein (VASP) was originally characterized as a substrate of both cGMP- and cAMP-dependent kinases (PKG and PKA, or cGPK and cAPK, respectively) (1). It is now believed that VASP belongs to the Ena/VASP family of adaptor proteins linking the cytoskeletal system to the signal transduction pathways and that it functions in cytoskeletal organization, fibroblast migration, platelet activation and axon guidance (2,3). Three phosphorylation sites, Ser157, Ser239, and Thr278, have been identified. Ser239 is the major PKG phosphorylation site while Ser157 is the major PKA phosphorylation site (4). Evidence suggests that VASP phosphorylation reduces its association with actin and has a negative effect on actin polymerization (5). Phosphorylation at Ser239 of VASP is a useful marker for monitoring PKG activation and signaling (6,7).

Background: Wiskott-Aldrich syndrome proteins (WASPs) mediate actin dynamics by activating the Arp2/3 actin nucleation complex in response to activated Rho family GTPases. In mammals, five WASP family members have been described. Hematopoietic WASP and ubiquitously expressed N-WASP are autoinhibited in unstimulated cells. Upon stimulation they are activated by cdc42, which relieves the autoinhibition in conjunction with phosphatidyl inositol 4,5-bisphosphate. Three WAVE (Wasf, SCAR) family proteins are similar in sequence to WASP and N-WASP but lack the WASP/N-WASP autoinhibition domains and are indirectly activated by Rac (reviewed in 1). Both WASP and WAVE functions appear to be essential, as knockout of either N-WASP or Scar-2 in mice results in cardiac and neuronal defects and embryonic lethality (2,3). Loss of WASP results in immune system defects and fewer immune cells (4). WAVE-2 (WASF2) is widely distributed, while WAVE-1 and WAVE-3 are strongly expressed in brain (5). WAVE-3 may act as a tumor suppressor in neuroblastoma, a childhood disease of the sympathetic nervous system (6). Increased expression of WAVE-3 is seen in breast cancer, and studies in breast adenocarcinoma cells indicate that WAVE-3 regulates breast cancer progression, invasion and metastasis through the p38 mitogen-activated protein kinase (MAPK) pathway (7,8).

Background: Microtubules (MTs) are polarized cellular filaments composed of α/β tubulin heterodimers. The slower growing (minus) microtubule ends are located at MT organizing centers (MTOCs), with the faster growing (plus) ends extending to the cell periphery. The regulation of MT dynamics is an important part of several biological processes, including cell division, migration, adhesion, membrane trafficking, and polarity (1).Human cytoplasmic linker-associate proteins 1 and 2 (CLASP1 and CLASP2) are evolutionarily conserved proteins that localize to the plus ends of interphase microtubules. During mitosis, CLASP 1 and CLASP2 localize to the centrosomes and kinetochores (KT) where they regulate mitotic spindle positioning to ensure proper chromosome alignment (2,3). Research studies indicate that phosphorylation of the carboxy terminus of CLASP2 during mitosis by CDK1 and PLK1 is required for efficient mitotic MT-KT attachment (4). Phosphorylation of CLASP2 at Ser1013 is a critical step that primes CLASP2 for further phosphorylation by PLK1 (4). The additional phosphorylation of CLASP2 at Ser533 and Ser537 by GSK3-3β controls the distribution of CLASP2 on MTs by inhibiting CLASP2 interaction with the Rac1/cdc42 effector protein IQGAP1 (5).

Background: TRPV4 is a member of the transient receptor potential vanilloid (TRPV) family of ion channels, and functions as a Ca2+-permeant non-selective cation channel. TRPV4 channels are expressed in many cell types, with particular abundance in sensory and spinal neurons (1). TRPV4 channels play a role in maintaining cellular homeostasis, by facilitating transmembrane Ca2+ transport in response to various stimuli, including thermal stress, fatty acid metabolites, and hypotonicity (2). Mutations in the TRPV4 gene have consequently been attributed to a variety of pathological conditions. For example, constitutively active TRPV4 mutants can lead to excess Ca2+ influx, resulting in toxicity and degeneration of peripheral nerves (3). TRPV4-dependent Ca2+ influx was also shown to mediate strain-induced and TGFβ1-induced epithelial-mesenchymal transition (EMT), suggesting a mechanistic role for TRPV4-mediated Ca2+ transport in fibrosis and oncogenesis (4). Consistent with this, studies in capillary endothelial cells showed that mechanical strain-induced Ca2+ influx through TRPV4 promote focal adhesion and stress fiber remodeling, mediated specifically through integrins, PI3K, and downstream kinases including Rho and ROCK (5).
