Crystal structure of an abridged SER to ALA mutant of the mature ectodomain of the human receptor-type protein-tyrosine phosphatase ICA512/IA-2 at pH 7.5

Template:ABSTRACT PUBMED 18048354

Function

[PTPRN_HUMAN] Implicated in neuroendocrine secretory processes. May be involved in processes specific for neurosecretory granules, such as their biogenesis, trafficking or regulated exocytosis or may have a general role in neuroendocrine functions. Seems to lack intrinsic enzyme activity. May play a role in the regulation of secretory granules via its interaction with SNTB2.^{[1] [2]}
