Arthropoda_PTN001056595 lost the glutamate receptor activity, but it should still have the receptor activity. Right now both are blank, and it is not possible to propagate receptor activity to the node.
Arthropoda_PTN001056595 - stop the propagation of dendrite. In the Annotation window, it shows the NOT annotation, but in the Matrix window, the NOT (red icon with X in the middle) is not shown.

# REFERENCE
Annotation inferences using phylogenetic trees
The goal of the GO Reference Genome Project, described in PMID 19578431, is to provide accurate, complete and consistent GO annotations for all genes in twelve model organism genomes. To this end, GO curators are annotating evolutionary trees from the PANTHER database with GO terms describing molecular function, biological process and cellular component. GO terms based on experimental data from the scientific literature are used to annotate ancestral genes in the phylogenetic tree by sequence similarity (ISS), and unannotated descendants of these ancestral genes are inferred to have inherited these same GO annotations by descent. The annotations are done using a tool called PAINT (Phylogenetic Annotation and INference Tool).
