Binding to a BH2 protein domain, present in Bcl-2 family members. Proteins that act as inhibitors of apoptosis harbour at least three BH domains: BH1, BH2 and BH3; the BH1 and BH2 domains are found in all death antagonists of the Bcl-2 family but only in one class of death agonists.

Binding to a BH1 protein domain, present in Bcl-2 family members. Proteins that act as inhibitors of apoptosis harbour at least three BH domains: BH1, BH2 and BH3; the BH1 and BH2 domains are found in all death antagonists of the Bcl-2 family but only in one class of death agonists.

Binding to a BH4 protein domain, present in Bcl-2 family members. All anti-apoptotic proteins contain BH1 and BH2 domains; some also contain an additional N-terminal BH4 domain, which is almost never seen in pro-apoptotic proteins. Loss of the BH4 domain can diminish or abrogate anti-apoptotic function or even impart outright death-promoting properties to the protein.

Binding to a BH3 protein domain, present in Bcl-2 family members. The BH3 domain is a potent death domain and has an important role in protein-protein interactions and in cell death.

OBSOLETE. A cell cycle process that modulates the frequency, rate or extent of ubiquitin ligase activity during the meiotic cell cycle.

OBSOLETE. Any process that stops, prevents, or reduces the frequency, rate or extent of ubiquitin ligase activity during the meiotic cell cycle.

OBSOLETE. Any process that activates, maintains or increases the rate of ubiquitin ligase activity during the meiotic cell cycle.

Binding to gonadotropin-releasing hormone (GnRH), a peptide hormone responsible for the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary. GnRH is synthesized and released by the hypothalamus.

Binding to thyrotropin-releasing hormone, a tripeptide hormone that stimulates the release of thyroid-stimulating hormone (TSH) and prolactin by the anterior pituitary and it is produced by the hypothalamus and travels across the median eminence to the pituitary via the pituitary portal system.

A nuclear body that reacts against SP100 auto-antibodies (PML = promyelocytic leukemia) located within a cell of a host organism.

Binding to a member of the FATZ family of proteins, filamin-, actinin-, and telethonin-binding proteins of the Z-disc of striated muscle. FATZ proteins are located in the Z-disc of the sarcomere and are involved in a complex network of interactions with other Z-band components.

OBSOLETE. Any process that stops, prevents, or reduces the frequency, rate or extent of the increase in size or mass of an organism, or the progression of an organism from an initial condition to a later condition, occurring in, on or near the exterior of its host organism.

OBSOLETE. Binding to Z-band alternatively spliced PDZ motif protein (ZASP). ZASP is a Z-band protein specifically expressed in heart and skeletal muscle. This protein contains N-terminal PDZ domain and C-terminal LIM domain.

OBSOLETE. The covalent alteration by an organism of one or more amino acids occurring in proteins, peptides and nascent polypeptides (co-translational, post-translational modifications) of the host organism. The host is defined as the larger of the organisms involved in a symbiotic interaction.

OBSOLETE. The alteration by an organism of protein levels in the host organism. The host is defined as the larger of the organisms involved in a symbiotic interaction.

Binding to muscle isoforms of actinin. Muscle alpha-actinin isoforms are found in skeletal and cardiac muscle and are localized to the Z-disc.
