Sprouty homolog 4

Spry4, Sprouty4
SPRY4 is an inhibitor of the receptor-transduced mitogen-activated protein kinase (MAPK) signaling pathway. It is positioned upstream of RAS (see HRAS; MIM 190020) activation and impairs the formation of active GTP-RAS (Leeksma et al., 2002 [PubMed 12027893]).[supplied by OMIM, Mar 2008] (from NCBI)

Zhang et al., Zhengzhou, China. In Pharm Biol, 01 Nov 2015
RESULTS AND CONCLUSION: DMU-212 was found to regulate a diverse range of genes, including cytokines (IL8, selectin E, MPZL2, EGR1, CCL20, ITGB8, CXCL1, VCAM1, KITLG, and AREG), transport proteins (TRPC4, SLC41A2, SLC17A5, and CREB5), metabolism (CYP1B1, CYP1A1, PDK4, CSNK1G1, MVK, TCEB3C, and CDKN3), enzymes (RAB23, SPHK1, CHSY3, PLAU, PLA2G4C, and MMP10), and genes involved in signal transduction (TMEM217, DUSP8, and SPRY4), chromosome organization (HIST1H2BH and GEM), cell migration and angiogenesis (ERRFI1, HBEGF, and NEDD9), and apoptosis (TNFSF15, TNFRSF9, CD274, BCL2L11, BIRC3, TNFAIP3, and TIFA), as well as other genes with unknown function (PGM5P2, SNORD1142, LOC151760, KRTAP5-2, C1orf110, SNORA14A, MIR31, C2CD4B, SCARNA4, C2orf66, SC4MOL, LOC644714, and LOC283392).

Cooperative loss of RAS feedback regulation drives myeloid leukemogenesis.
Lowe et al., New York City, United States. In Nat Genet, May 2015
We show that in mice, premalignant myeloid cells harboring a Kras(G12D) allele retained low levels of Ras signaling owing to negative feedback involving Spry4 that prevented transformation.
The role of microRNAs and long non-coding RNAs in the pathology, diagnosis, and management of melanoma.
Perera et al., Orlando, United States. In Arch Biochem Biophys, Jan 2015
Data are also emerging on the role of long non-coding RNAs (lncRNAs), such as SPRY4-IT1, BANCR, and HOTAIR, in melanomagenesis.
Autoregulatory loop between TGF-β1/miR-411-5p/SPRY4 and MAPK pathway in rhabdomyosarcoma modulates proliferation and differentiation.
Wang et al., Suzhou, China. In Cell Death Dis, Dec 2014
Using a luciferase reporting system and sequence analysis, the potential target of miR-411-5p was identified as sprouty homolog 4 (SPRY4), which inhibits protein kinase Cα-mediated activation of mitogen-activated protein kinases (MAPKs), especially p38MAPK phosphorylation.
