Gene Ontology (2, 2)

Asymmetric/Biological Unit(hide GO term definitions)

Chain A (ANP12_ZOAAM | P19614)

biological process
	GO:0050826	response to freezing	Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a freezing stimulus, temperatures below 0 degrees Celsius.
cellular component
	GO:0005576	extracellular region	The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
