Pleckstrin homology-like domain; The PH-like family includes the PH domain, both the Shc-like and IRS-like PTB domains, the ran-binding domain, the EVH1 domain, a domain in neurobeachin and the third domain of FERM. All of these domains have a PH fold, but lack significant sequence similarity. They are generally involved in targeting to protein to the appropriate cellular location or interacting with a binding partner. This domain family possesses multiple functions including the ability to bind inositol phosphates and to other proteins. The actual alignment was detected with superfamily member cd14678: Pssm-ID: 473070 Cd Length: 105 Bit Score: 32.41 E-value: 7.51e-03

Pleckstrin homology (PH) domain of Downstream of tyrosine kinase 4, 5, and 6 proteins; The Dok family adapters are phosphorylated by different protein tyrosine kinases. Dok proteins are involved in processes such as modulation of cell differentiation and proliferation, as well as in control of the cell spreading and migration The Dok protein contains an N-terminal pleckstrin homology (PH) domain followed by a central phosphotyrosine binding (PTB) domain, which has a PH-like fold, and a proline- and tyrosine-rich C-terminal tail. The PH domain binds to acidic phospholids and localizes proteins to the plasma membrane, while the PTB domain mediates protein-protein interactions by binding to phosphotyrosine-containing motifs. The C-terminal part of Dok contains multiple tyrosine phosphorylation sites that serve as potential docking sites for Src homology 2-containing proteins such as ras GTPase-activating protein and Nck, leading to inhibition of ras signaling pathway activation and the c-Jun N-terminal kinase (JNK) and c-Jun activation, respectively. There are 7 mammalian Dok members: Dok-1 to Dok-7. Dok-1 and Dok-2 act as negative regulators of the Ras-Erk pathway downstream of many immunoreceptor-mediated signaling systems, and it is believed that recruitment of p120 rasGAP by Dok-1 and Dok-2 is critical to their negative regulation. Dok-3 is a negative regulator of the activation of JNK and mobilization of Ca2+ in B-cell receptor-mediated signaling, interacting with SHIP-1 and Grb2. Dok-4- 6 play roles in protein tyrosine kinase(PTK)-mediated signaling in neural cells and Dok-7 is the key cytoplasmic activator of MuSK (Muscle-Specific Protein Tyrosine Kinase). In general, PH domains have diverse functions, but are generally involved in targeting proteins to the appropriate cellular location or in the interaction with a binding partner. They share little sequence conservation, but all have a common fold, which is electrostatically polarized. PH domains are found in cellular signaling proteins such as serine/threonine kinase, tyrosine kinases, regulators of G-proteins, endocytotic GTPases, adaptors, as well as cytoskeletal associated molecules and in lipid associated enzymes.
