GO:0051393 alpha-actinin binding Interacting selectively and non-covalently with alpha-actinin, one of a family of proteins that cross-link F-actin as antiparallel homodimers. Alpha-actinin has a molecular mass of 93-103 KDa; at the N-terminus there are two calponin homology domains, at the C-terminus there are two EF-hands. These two domains are connected by the rod domain. This domain is formed by triple-helical spectrin repeats. 2
GO:0001093 TFIIB-class transcription factor binding Interacting selectively and non-covalently with a basal RNA polymerase II transcription factor of the TFIIB class, one of the factors involved in formation of the preinitiation complex (PIC) by RNA polymerase II and defined as a basal or general transcription factor. 2
GO:0031434 mitogen-activated protein kinase kinase binding Interacting selectively and non-covalently with a mitogen-activated protein kinase kinase, any protein that can phosphorylate a MAP kinase. 2
GO:0071987 WD40-repeat domain binding Interacting selectively and non-covalently with a WD40 repeat domain of a protein. The WD40 repeat is a short structural motif of approximately 40 amino acids, often terminating in a tryptophan-aspartic acid (W-D) dipeptide. Several of these repeats are combined to form a type of protein domain called the WD domain. 1
GO:0005520 insulin-like growth factor binding Interacting selectively and non-covalently with an insulin-like growth factor, any member of a group of polypeptides that are structurally homologous to insulin and share many of its biological activities, but are immunologically distinct from it. 1
GO:0045309 protein phosphorylated amino acid binding Interacting selectively and non-covalently with a phosphorylated amino acid residue within a protein. 1
GO:0045545 syndecan binding Interacting selectively and non-covalently with syndecan, an integral membrane proteoglycan (250-300 kDa) associated largely with epithelial cells. 1
GO:0001156 TFIIIC-class transcription factor binding Interacting selectively and non-covalently with an RNA polymerase III transcription factor of the TFIIIC class, one of the factors involved in formation of the preinitiation complex (PIC) by RNA polymerase III. 1
GO:0019862 IgA binding Interacting selectively and non-covalently with an immunoglobulin of an IgA isotype. 1
GO:0032036 myosin heavy chain binding Interacting selectively and non-covalently with a heavy chain of a myosin complex. 1
GO:0036033 mediator complex binding Interacting selectively and non-covalently with a mediator complex. The mediator complex is a protein complex that interacts with the carboxy-terminal domain of the largest subunit of RNA polymerase II and plays an active role in transducing the signal from a transcription factor to the transcriptional machinery. The Saccharomyces complex contains several identifiable subcomplexes: a head domain comprising Srb2, -4, and -5, Med6, -8, and -11, and Rox3 proteins; a middle domain comprising Med1, -4, and -7, Nut1 and -2, Cse2, Rgr1, Soh1, and Srb7 proteins; a tail consisting of Gal11p, Med2p, Pgd1p, and Sin4p; and a regulatory subcomplex comprising Ssn2, -3, and -8, and Srb8 proteins. Metazoan mediator complexes have similar modular structures and include homologs of yeast Srb and Med proteins. 1
GO:0005518 collagen binding Interacting selectively and non-covalently with collagen, a group of fibrous proteins of very high tensile strength that form the main component of connective tissue in animals. Collagen is highly enriched in glycine (some regions are 33% glycine) and proline, occurring predominantly as 3-hydroxyproline (about 20%). 1
GO:0017075 syntaxin-1 binding Interacting selectively and non-covalently with the SNAP receptor syntaxin-1. 1
GO:0050692 DBD domain binding Interacting selectively and non-covalently with the DBD, DNA binding domain, of a protein. The DNA binding domain of the vitamin D receptor, one of a family of receptors with the DBD, is split into three regions, the P, D and T boxes. Residues that are critical for target sequence selectivity form the P-box. The D-box contains residues that are important for homodimerization of class I nuclear receptors. The T-box is essential for both DNA-binding and transactivation of the VDR; this region may also be important for dimerization with RXR for class II nuclear receptors. 1
GO:0070064 proline-rich region binding Interacting selectively and non-covalently with a proline-rich region, i.e. a region that contains a high proportion of proline residues, in a protein. 1
