"The specification of the anterior/posterior axis of the embryo by products of genes expressed in the zygote; exemplified in insects by the gap genes, pair rule genes and segment polarity gene cascade [goid 7354] [evidence IEA]; The establishment of an organism's body plan or part of an organism with respect to the left and right halves. The pattern can either be symmetric, such that the halves are mirror images, or asymmetric where the pattern deviates from this symmetry [goid 7368] [evidence IEA]; The chemical reactions and pathways involving glycoproteins, any protein that contains covalently bound glycose (i.e. monosaccharide) residues other than as a moiety of nucleic acid; the glycose occurs most commonly as oligosaccharide or fairly small polysaccharide but occasionally as monosaccharide [goid 9100] [pmid 8218226] [evidence IDA]; Any process that modulates the frequency, rate or extent of the activity of any BMP receptor signaling pathway [goid 30510] [pmid 10467177] [evidence TAS]; The generation of a mature nerve growth factor by proteolysis of a precursor [goid 32455] [pmid 12787574] [evidence EXP]; The appearance of nerve growth factor due to biosynthesis or secretion by cells in a neuron's target field, resulting in an increase in its intracellular or extracellular levels [goid 32902] [pmid 8615794] [evidence IDA]; The regulated release of a substance by a cell [goid 32940] [pmid 8615794] [evidence IDA]; The hydrolysis of a peptide bond or bonds within a protein during protein maturation, the process leading to the attainment of the full functional capacity of a protein [goid 51605] [pmid 9242664] [evidence IDA]; The hydrolysis of a peptide bond or bonds within a protein during protein maturation, the process leading to the attainment of the full functional capacity of a protein [goid 51605] [pmid 9738469] [evidence IDA]; The hydrolysis of a peptide bond or bonds within a protein during protein maturation, the process leading to the attainment of the full functional capacity of a protein [goid 51605] [pmid 8218226] [evidence IDA]"
