This entry represents a group of dsDNA Baculovirus proteins. It is required for the infectivity of the OBs or occlusion bodies. It is a structural protein of the ODV envelope required only in the first steps of per os larva infection, as viruses being produced in cells expressing the gene for this protein but not containing it in their genomes are able to produce successful infections. Baculoviruses are large DNA viruses that infect arthropods, mainly members of the order Lepidoptera. In their life cycle, they produce two kinds of particles, a budded, non-occluded virus (BV), which buds out of the infected cell and is responsible for the cell-to-cell transmission of the virus, and an occluded form, the occlusion body (OB), which is responsible for protecting the virus between encounters with larvae. A variable number of virions are included in the para-crystalline structure of the OB, mainly constituted by the virus-encoded polyhedrin protein; these virions are called occlusion body-derived virions or ODVs [].
This entry represents the SH2 domain of Grb14. The Grb7 (growth factor receptor-bound 7) family includes Grb7, Grb10, and Grb14. These are adapter proteins mediating signal transduction from multiple cell surface receptors to diverse downstream pathways. They are composed of an N-terminal proline-rich domain, a Ras Associating-like (RA) domain, a Pleckstrin Homology (PH) domain, a PIR (phosphorylated insulin receptor interacting region) domain (also known as the family-specific BPS region), and a C-terminal SH2 domain []. Grb14 binds to various receptor tyrosine kinases (RTKs) under ligand induction. This interaction involves the SH2 and PIR domains [].

Grb10 inhibits insulin receptor kinase activity and mediates insulin-stimulated degradation of the insulin receptor []. It binds to the regulatory kinase loop of the insulin receptor (IR) via its SH2 and BPS domains []. Grb10 is directly phosphorylated by mTORC1 and may participate in a feedback inhibition of the phosphatidylinositol 3-kinase (PI3K) and extracellular signal-regulated, mitogen-activated protein kinase (ERK-MAPK) pathways [].
