The differentiation of cells that will contribute to the structure and function of the hypothalamus.

The process in which the migration of an axon growth cone of a pyramidal cell that is part of the corticospinal tract is directed after decussation through the spinal cord in response to a combination of attractive and repulsive cues.

The process in which the migration of an axon growth cone of a pyramidal cell that is part of the corticospinal tract is directed to cross the midline to the contralateral side.

The recognition of molecules at the central nervous system midline choice point by an axon growth cone; this choice point determines whether the growth cone will cross the midline.

The process in which the migration of an axon growth cone of a pyramidal cell that is part of the corticospinal tract is directed after exiting the cerebral peduncle through the basilar pons in response to a combination of attractive and repulsive cues.

The process in which the migration of an axon growth cone of a pyramidal cell that is part of the corticospinal tract is directed after exiting the basilar pons through the medullary pyramid in response to a combination of attractive and repulsive cues.

Any process that stops, prevents, or reduces the frequency, rate or extent of phosphorus utilization.

The component of the endosome membrane consisting of the gene products and protein complexes having either part of their peptide sequence embedded in the hydrophobic region of the membrane or some other covalently attached group such as a GPI anchor that is similarly embedded in the membrane.

The component of the endosome membrane consisting of the gene products having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.

The component of the mitochondrial inner membrane consisting of the gene products and protein complexes having either part of their peptide sequence embedded in the hydrophobic region of the membrane or some other covalently attached group such as a GPI anchor that is similarly embedded in the membrane.

The component of the mitochondrial membrane consisting of the gene products and protein complexes having either part of their peptide sequence embedded in the hydrophobic region of the membrane or some other covalently attached group such as a GPI anchor that is similarly embedded in the membrane.

The component of the mitochondrial inner membrane consisting of the gene products having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.

The component of the mitochondrial membrane consisting of the gene products having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.

The component of the mitochondrial outer membrane consisting of the gene products and protein complexes having either part of their peptide sequence embedded in the hydrophobic region of the membrane or some other covalently attached group such as a GPI anchor that is similarly embedded in the membrane.

The component of the mitochondrial outer membrane consisting of the gene products having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.

The component of the nuclear outer membrane consisting of the gene products and protein complexes having either part of their peptide sequence embedded in the hydrophobic region of the membrane or some other covalently attached group such as a GPI anchor that is similarly embedded in the membrane.

The component of the nuclear outer membrane consisting of the gene products having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.

The initial step of transcription, consisting of the assembly of the RNA polymerase preinitiation complex (PIC) at a gene promoter, as well as the formation of the first few bonds of the RNA transcript. Transcription initiation includes abortive initiation events, which occur when the first few nucleotides are repeatedly synthesized and then released, and ends when promoter clearance takes place.
