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)

We found that IGFBP5 (insulin-like growth factor binding protein 5), PLAT (plasminogen activator), SNAI2 (snail homolog 2), JAG1 (jagged 1), SPRY4 (Sprouty homolog 4), and CD44 were upregulated, whereas CFB (complement factor B), VCAM1 (vascular cell adhesion molecule 1), AQP1 (aquaporin 1), LOXL1 (lysyl oxidase-like 1), and RBPMS (RNA-binding protein with multiple splicing) were down- regulated in both radiation-damaged and old cells.

Pitteloud et al., Lausanne, Switzerland. In Am J Hum Genet, Jun 2013
Except for FGF18 and SPRY2, all other genes were found to be mutated in CHH individuals: FGF17 (n = 3 individuals), IL17RD (n = 8), DUSP6 (n = 5), SPRY4 (n = 14), and FLRT3 (n = 3).

Sprouty2 and -4 regulate axon outgrowth by hippocampal neurons.
Klimaschewski et al., Innsbruck, Austria. In Hippocampus, 2012
our results imply that Sprouty2 and -4 are downregulated in the hippocampus during postnatal brain development and that they can act as regulators of developmental axon growth.

Regulation of tooth number by fine-tuning levels of receptor-tyrosine kinase signaling.
Klein et al., San Francisco, United States. In Development, 2011
Interestingly, changes in sprouty gene dosage led to a graded change in incisor number, with progressive decreases in sprouty dosage leading to increasing numbers of teeth.
