Summary
PTPN21 (protein tyrosine phosphatase non-receptor type 21, HGNC:9651) is a protein-coding gene on chromosome 14q31.3, encoding Tyrosine-protein phosphatase non-receptor type 21 (Q16825).
The protein encoded by this gene is a member of the protein tyrosine phosphatase (PTP) family. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. This PTP contains an N-terminal domain, similar to cytoskeletal- associated proteins including band 4.1, ezrin, merlin, and radixin. This PTP was shown to specially interact with BMX/ETK, a member of Tec tyrosine kinase family characterized by a multimodular structures including PH, SH3, and SH2 domains. The interaction of this PTP with BMX kinase was found to increase the activation of STAT3, but not STAT2 kinase. Studies of the similar gene in mice suggested the possible roles of this PTP in liver regeneration and spermatogenesis.

Literature-anchored findings (GeneRIF, showing 9)
- PTPD1 is a component of a multivalent scaffold complex nucleated by FAK at specific intracellular sites (PMID:18223254)
- In colorectal tumors, microsatellite repeats mutation rates are higher than the mean mutation frequency; the highest mutation frequency among 16 PTP genes (PMID:19000305)
- PTPD1 is a novel component of the endocytic machinery that impacts on EGF receptor stability and on growth and motility of bladder cancer cells (PMID:20923765)
- The results that 2 non-synonymous markers in PTPN21 are associated with schizophrenia, further investigation of this locus is warranted. (PMID:21752600)
- Presented data suggest that the transient formation of dynamic PTPD1/EGFR signalling complexes strengthens EGF signalling by promoting the spatial propagation of EGFR phosphorylated species (PMID:25062045)
- Study demonstrates that PTPN21 activates KIF1C by binding to the stalk region. This function does not require catalytic activity of the phosphatase, and its N-terminal FERM domain alone is sufficient to stimulate the transport of KIF1C cargoes in cells as well as increasing the landing rate of KIF1C on microtubules in vitro. The cargo adapter Hook3 binds KIF1C in the same region and activates KIF1C in a similar way. (PMID:31217419)

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 57 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
