protein targeting to lysosome

The process of directing proteins towards the lysosome using signals contained within the protein.

GO:0007165

signal transduction

The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell.

vesicle organization

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of a vesicle.

NAS

GO:0016197

endosomal transport

The directed movement of substances into, out of, or mediated by an endosome, a membrane-bounded organelle that carries materials newly ingested by endocytosis. It passes many of the materials to lysosomes for degradation.

IMP

GO:0030100

regulation of endocytosis

Any process that modulates the frequency, rate or extent of endocytosis.

TAS

BP

GO:0030509

BMP signaling pathway

A series of molecular signals initiated by the binding of a member of the BMP (bone morphogenetic protein) family to a receptor on the surface of a target cell, and ending with regulation of a downstream cellular process, e.g. transcription.

TAS

CC

GO:0005737

cytoplasm

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

IDA

CC

GO:0005769

early endosome

A membrane-bounded organelle that receives incoming material from primary endocytic vesicles that have been generated by clathrin-dependent and clathrin-independent endocytosis; vesicles fuse with the early endosome to deliver cargo for sorting into recycling or degradation pathways.

IDA

CC

GO:0031901

early endosome membrane

The lipid bilayer surrounding an early endosome.

TAS

CC

GO:0043231

intracellular membrane-bounded organelle

Organized structure of distinctive morphology and function, bounded by a single or double lipid bilayer membrane and occurring within the cell. Includes the nucleus, mitochondria, plastids, vacuoles, and vesicles. Excludes the plasma membrane.

IDA

MF

GO:0005515

protein binding

Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).

IPI

MF

GO:0005545

1-phosphatidylinositol binding

Interacting selectively and non-covalently with phosphatidylinositol, any glycophospholipid with its sn-glycerol 3-phosphate residue is esterified to the 1-hydroxyl group of 1D-myo-inositol.

IDA

MF

GO:0005547

phosphatidylinositol-3,4,5-trisphosphate binding

Interacting selectively and non-covalently with phosphatidylinositol-3,4,5-trisphosphate, a derivative of phosphatidylinositol in which the inositol ring is phosphorylated at the 3', 4' and 5' positions.

IDA

MF

GO:0008565

protein transporter activity

Enables the directed movement of proteins into, out of or within a cell, or between cells.

IMP

MF

GO:0046872

metal ion binding

Interacting selectively and non-covalently with any metal ion.
