Would you please mention the target organism for your proteins? Then, there is possibility to introduce some python modules or R packages for supporting you for that goal you have. There is another simplest way to easily find the common networks for your proteins. Before spending your time with any software, it is better you classify your protein entities based on their function. For example, how many protein kinase targets are existed in your list? Generally, kinases shared common roles inside the living cells and by this way you can find the most relevant pathways for these targets. However, if your proteins list only covered human records you should use human protein atlas to find the simplified pathways for them. After this step, you can use Path2PPI package in R software to precisely mange your queries.
