MOTIVATION Protein domains are subunits that can fold and evolve independently. Identification of domain boundary locations is often the first step in protein folding and function annotations. Most of the current methods deduce domain boundaries by sequence-based analysis, which has low accuracy. There is no efficient method for predicting discontinuous(More)
The p21-activated protein kinases (Paks) have been implicated in the regulation of smooth muscle contractility, but the physiologic effects of Pak activation on airway reactivity in vivo are unknown. A mouse model with a genetic deletion of Pak1 (Pak1(-/-)) was used to determine the role of Pak in the response of the airways in vivo to challenge with(More)
Activation of Wingless (Wnt)/beta-catenin signaling is a hallmark of colorectal carcinoma (CRC). It is very important to find out the molecular mechanism for the hyperactivation of Wnt/beta-catenin signaling and identify novel therapeutic targets. Kindlin-2, a regulator of integrins, recently has been found to be involved in the tumorigenesis. However, its(More)
Neuropeptides play a variety of roles in many physiological processes and serve as potential therapeutic targets for the treatment of some nervous-system disorders. In recent years, there has been a tremendous increase in the number of identified neuropeptides. Therefore, we have developed NeuroPep, a comprehensive resource of neuropeptides, which holds(More)
A variety of protein domain predictors were developed to predict protein domain boundaries in recent years, but most of them cannot predict discontinuous domains. Considering nearly 40% of multidomain proteins contain one or more discontinuous domains, we have developed DomEx to enable domain boundary predictors to detect discontinuous domains by assembling(More)
