Chain A (SAMN1_HUMAN | Q9NSI8)

molecular function
	GO:0001784	phosphotyrosine residue binding	Interacting selectively and non-covalently with a phosphorylated tyrosine residue within a protein.
biological process
	GO:0050869	negative regulation of B cell activation	Any process that stops, prevents, or reduces the frequency, rate or extent of B cell activation.
	GO:0002820	negative regulation of adaptive immune response	Any process that stops, prevents, or reduces the frequency, rate, or extent of an adaptive immune response.
	GO:0050732	negative regulation of peptidyl-tyrosine phosphorylation	Any process that stops, prevents, or reduces the frequency, rate or extent of the phosphorylation of peptidyl-tyrosine.
cellular component
	GO:0042995	cell projection	A prolongation or process extending from a cell, e.g. a flagellum or axon.
	GO:0005737	cytoplasm	All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
	GO:0005829	cytosol	The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
	GO:0005634	nucleus	A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
	GO:0001726	ruffle	Projection at the leading edge of a crawling cell; the protrusions are supported by a microfilament meshwork.
