FunPred-1: Protein function prediction from a protein interaction network using neighborhood analysis

Abstract: Abstract:Proteins are responsible for all biological activities in living organisms. Thanks to genome sequencing projects, large amounts of DNA and protein sequence data are now available, but the biological functions of many proteins are still not annotated in most cases. The unknown function of such non-annotated proteins may be inferred or deduced from their neighbors in a protein interaction network. In this paper, we propose two new methods to predict protein functions based on network neighborhood proper… Show more

“…Protein clusters, thus formed, comprises of proteins belonging to any functional group. It results in accumulating larger number of functional groups as compared with only eight functional groups in our previous work (Saha et al, 2014). The novel computational method works in two stages: All the unique proteins are first clustered into M mutually exclusive clusters based on their node weight and edge weight in the overall PPIN.…”

“…It highlights the fact that most of the admissible results are successfully generated by FunPred 3.0. Table 4 shows a detailed performance comparison of other methodologies along with our proposed systems (like FunPred 1.1, FunPred 1.2 (Saha et al, 2014)), the neighborhood counting method (Schwikowski, Uetz & Fields, 2000), the Chi-square method (Hishigaki et al, 2001), a recent version of the neighbor relativity coefficient (NRC) (Moosavi, Rahgozar & Rahimi, 2013), FPred_Apriori (Prasad et al, 2017), Zhang methodology (Zhang et al, 2009), domain combination similarity (DCS) (Peng et al, 2014), domain combination similarity in context of protein complexes (DSCP) (Peng et al, 2014), protein overlap network (PON) (Liang et al, 2013), Deep_GO (Kulmanov et al, 2018) and the FS-weight based method (Chua, Sung & Wong, 2006)). All these data are collected from their respective works which are executed on the same organism, that is, yeast.…”

“…To discover more candidate genes involved in SPN, we conducted a search in the GRN of SPN based on the “guilt-by-association” rule [ 29 ] which has been widely used to predict gene functions in many biological networks [ 55 , 56 ]. The rule regarded the neighbors of a given gene as to have similar biological functions.…”
